Her extraordinary discoveries made more understandable Calcium uptake by leafy vegetables crops causing disappearing Calcium deficiency disorders on plants, which made possible to reduce the spray of Ca solutions on leaves to correct the disorder.
An additional discovery is also helping to improve a vegetable crop (tomato) performance. A literature search revealed no publications on the effect of effective microorganisms (EM) on the growth parameters of tomato transplants. Transplants with EM were significantly shorter and had a greater stem diameter than those without EM. EM improved the quality of tomato transplants, as they remained more compact with a greater stem diameter.
She also was one of the first to find out that Silicon improves vegetables transplants quality. In her trial silicic acid was applied as an aqueous spray applied in different concentrations from the first true leaf stage three times at two-week intervals. Tomato transplants were taller with larger stem diameters when treated with Si.
Further more she discovered while testing legume crops under project EUROLEGUME that choosing the right sowing rate can be crucial component for certain field pea varieties in improving their yield quality – protein yield! INNOVATION: Highest protein yield came from varieties Capella, Clara and Kirke. For those three varieties there is a trend that sowing rate increases the protein yield.
By writing those books it can be seen her hard work and dedication to her profession - vegetable crop research.
Olle, M. 2021. Best practices against calcium deficiency in greenhouse plant production (hardcover). USA: Amazon Media EU S.à r.l. 109p.

This book aims to describe best practices against calcium deficiency in greenhouse crop production and how those methods can improve the growth, yield, quality, and protection of greenhouse crops.
The first article gives an overview of the causes and control of calcium-deficiency disorders in vegetables.
The second and third chapters are about my two discoveries:
1. Plants were grown under a far-red filter, which filters out much of far-red light. Far-red light is responsible for the elongation of plants. When grown under a far-red filter to remove much of the far-red light then plants remain more compact (knowledge from Japan). With far-red filter plants contain more Calcium and show fewer Ca deficiency symptoms (Margit Olle discovery).
2. Negative DIF is when the night temperature is higher than the day temperature. In such condition’s plants stay more compact (Roar Moe from Norway have lots of papers about it). Under negative DIF conditions plants contain more Calcium and there are fewer Ca deficiency symptoms on plants (Margit Olle discovery).
The fourth article concluded that optimal size of rock wool cubes for chervil plants in present investigation was 135 cm3. The optimal pot volume for leaf lettuce plants was 0.6 L. The plants grown in those kinds of conditions had reduced amount of tipburned leaves, highest fresh weight and Ca content in leaves.
The fifth article showed that spraying with calcium reduced the incidence of calcium deficiency injury on plants. The incidence of tipburn increased with increase in salinity. It means adequate salinity levels should be used for each greenhouse crop production.
In conclusion all those best practices – negative DIF, far red filter, optimal volume of growing medium, spraying with Ca solutions and keeping adequate electrical conductivity – are the best tools to decrease the level of calcium deficiency in greenhouse crops.

Olle, M. 2021. Best practices in greenhouse plant production (hardcover). USA: Amazon Media EU S.à r.l. 89p. 

This book aims to describe best practices in greenhouse crop production and how those methods can improve the growth, yield, quality, and protection of greenhouse crops.
First three chapters are about my three discoveries:
1. Plants were grown under a far-red filter, which filters out much of far-red light. Far-red light is responsible for the elongation of plants. When grown under a far-red filter to remove much of the far-red light then plants remain more compact (knowledge from Japan). With far-red filter plants contain more Calcium and show fewer Ca deficiency symptoms (Margit Olle discovery).
2. Negative DIF is when the night temperature is higher than the day temperature. In such condition’s plants stay more compact (Roar Moe from Norway have lots of papers about it). Under negative DIF conditions plants contain more Calcium and there are fewer Ca deficiency symptoms on plants (Margit Olle discovery).
3. Effective microorganisms (EM) improve the quality of tomato transplants because they remain compact with greater stem diameter (Margit Olle discovery).
Bokashi tea improves the growth of tomato transplants by increasing stem diameter and is allowing for pants to take up more nutrients.
Cucumber transplants were taller and stem diameter was greater in silicic acid treatment compared to control. The content of NO3, N, P, Mg were higher in Si treated plants.
Out of the results of vermicompost substrates experiments we could conclude that the best substrate to grow cress is substrate containing 25% vermicompost, peat, gravel, light gravel.
In conclusion all those best practices – negative DIF, far red filter, EM, bokashi tea, silicic acid and vermicompost – are meant to use in greenhouses. They have huge potential to apply in organic and sustainable cropping systems.

Olle, M. 2021. Best effective microorganisms practices in greenhouse plant production (hard cover). USA: Amazon Media EU S.à r.l. 99p.

This book aims to illustrate the nature of EM and Bokashi technology and describe the best methods how EM and Bokashi technology can improve the growth, yield, quality, and protection of greenhouse crops.
EM can improve the quality and yield of vegetables by reducing the incidence of pests and diseases, and by protecting against weeds, thereby contributing to sustainable agriculture. Bokashi technology – coming from Asia (Japan) - is an innovative technology to improve soil fertility, plant health, yield and food quality. This technology has a huge potential to be applied in Europe, only right methodology should be developed based on the knowledge of temperature regimes. EM has been found to increase seed germination, vigour, early fruiting and the number of fruits in tomato. In most cases, it has also increased yield, probably due to increased photosynthesis. It is beneficial for pest management in tomato cultivation having pesticidal qualities. Applied with organic amendments it has enhanced weed growth in the first year which then declined significantly with time. It gave lower glycoalkaloid content in Bokashi-treated tomatoes. EM treatment increased vitamin C concentration and the content of saccharide, protein and amino acid in tomato. EM increased leaf N content and decreased leaf dry matter yield of tomatoes. EM improve the quality of tomato transplants, as they remained more compact with a greater stem diameter. EM improves the growth and reduces the nitrate content of cucumber, pumpkin and squash transplants. Bokashi tea improves the growth of tomato transplants by increasing stem diameter and is allowing for pants to take up more nutrients.
In conclusion all those best effective microorganism practices to use in greenhouses have huge potential to apply in organic and sustainable cropping systems in greenhouses – id est. to improve the growth, yield, quality, and protection of greenhouse crops and grow healthy food crops without harmful pesticide usage.

Olle, M. 2021. Innovative technologies for sustainable crop production (hardcover). USA: Amazon Media EU S.à r.l., 83p. 
This book contains 4 different chapters and shows how bokashi, effective microorganisms, Silicon and vermicompost influence the growth, yield and quality of vegetable production.
Bokashi technology – coming from Asia (Japan) - is an innovative technology to improve soil fertility, plant health, yield and food quality. This technology has a huge potential to be applied in Europe, only right methodology should be developed based on the knowledge of temperature regimes EM will influence the crop production. EM can improve the quality and yield of vegetables by reducing the incidence of pests and diseases, and by protecting against weeds, thereby contributing to sustainable agriculture. SAAT increases root system size, length of stem/tillers, leaf area, chlorophyll content and nutrient uptake, resulting in higher yield and improved. SAAT decreases effect of biotic and abiotic stresses. Therefore, SAAT is proposed as an element in sustainable cropping strategies. Vermicompost produced by the activity of earthworms is rich in macro and micronutrients, vitamins, growth hormones, enzymes such as proteases, amylases, lipase, cellulase and chitinase and immobilized microflora. Vermicompost boost all horticultural crops (cress, basil, radish, cabbage, tomato, cucumber, cabbage) growth in greenhouses without agrochemicals.
In conclusion all those innovative technologies have huge potential to apply in organic and sustainable cropping systems – id est. to grow healthy food crops without usage of harmful plant protection products.

Olle, M. 2015. Methods to avoid Calcium deficiency on greenhouse grown leafy crops. LAP LAMBERT Academic Publishing. 89 p.

This book presents an overview of methods used to counter Calcium deficiency on chervil, parsley and lettuce.

Physiological calcium deficiency has been an economic problem for vegetable growers for many years.

While this disorder has probably always been present, the problem has become more severe in recent years, perhaps because more intensive production practices are being used.

Calcium deficiency is usually related to the inability of the plant to translocate adequate calcium to the affected plant part rather than to insufficient soil calcium levels.  

First time ever chervil tipburn symptoms description in literature.

Best methods against Ca deficiency are:

• spraying leaves with Ca solution,

• growing plants under fluorescent lamps compared to high pressure mercury or high pressure sodium lamps. It was used first time against calcium deficiency. It was successful because lamps have very different light spectrum.

• growing plants under far red filter (discovery),

• growing plants in Negative DIF conditions (discovery).

Olle, M. 2020. Silicon as a challenge for sustainable vegetable crop production. USA: Amazon Media EU S.à r.l. , (in English), 88 pp.

This book contains 6 different scientific articles and shows how the growth, yield and nutrient content of vegetables in crop production can be influenced by Silicon treatment. The first article is a review article about how silicon (Si) influences agricultural production. The second article is about Silicon influence on tomato transplants growth. The third article is about Silicon influence on cucumber transplants growth. The fourth article is about Silicon influence on iceberg lettuce growth and nutrient content. The fifth article shows the effect Silicon influence on leaf lettuce growth and nutrient content. The sixth paper talks about how Silicon treatment influences the nutrient content of field pea seeds. Si is a second most abundant element both on the surface of the earth and in the soil. The Si in plants leads to an increase in horticulture production. It has been demonstrated to have multiple direct and indirect beneficial effects on growth and development of many plants. The beneficial effects of Si are especially pronounced in the plants exposed to abiotic and biotic stresses. Si enhances tolerance of plants to metals toxicity. Si uptake by plants improves agricultural crop quality and yield. Si application could therefore improve crop production under adverse climate and soil conditions. Si can influence positively plant growth and yield, in particular, under stress conditions. Si may increase the uptake and translocation of mineral elements in plants.

Olle, M. 2020. Vermicompost is boosting greenhouse vegetable production. USA: Amazon Media EU S.à r.l. (in English), 101 pp.

Vermicompost produced by the activity of earthworms is rich in macro and micronutrients, vitamins, growth hormones, enzymes such as proteases, amylases, lipase, cellulase and chitinase and immobilized microflora. The enzymes continue to disintegrate organic matter even after they have been ejected from the worms. Reduced use of water for irrigation, reduced pest attack, reduced termite attack, reduced weed growth; faster rate of seed germination and rapid seedlings growth and development; greater numbers of fruits per plant (in vegetable crops) and greater numbers of seeds per year (in cereal crops) are only some of the beneficial effects of the vermicompost usage in agricultural production. In my trials, vermicompost boosted all horticultural crops (cress, basil, radish, cabbage, tomato, cucumber, cabbage) growth in greenhouses without agrochemicals. This book contains 7 different scientific articles and shows how the growth and quality of indoor vegetable production can be influenced by adding vermicompost to growth substrates.
