Manganese (Mn) is an essential micronutrient that while needed in small amounts, plays a key role in photosynthesis. Mn sparks the photosynthesis process by splitting water after Photosytem II (PSII) fixes light to initiate the conversion of CO₂ and water into carbohydrates.

Manganese deficiency is widespread in Canadian Prairies and Eastern Canada, reducing growth and development of many crops and restricting yields and quality. In this post we will specifically examine the role of manganese in plants, the consequences if its deficiency and provide solutions to mitigate the crop stress due to manganese shortage or deficiency.

Calcium is an essential nutrient that allows plants to grow, develop, remain healthy and reproduce optimally to form seeds or fruits. Although it’s considered a secondary nutrient, a plant’s need for calcium can be as high as its needs for primary nutrients such as nitrogen and potassium.

Soil pH is a key factor in farmland as it controls availability of nutrients, microbial activity and crop productivity. Before delving into what causes soils to become acid or alkaline and the steps to take to treat and correct soil pH, we must first establish what is considered an optimal pH for crop production.

Soil pH is a key factor in farmland as it controls availability of nutrients, microbial activity and crop productivity. Before delving into what causes soils to become acid and the steps to take to treat and correct acidic soil, we must first establish what is considered an optimal pH for crop production.

For most prairie crops, a soil pH range of 6.0 to 8.0 is suitable for optimal growth and development. Soils with pH ranging from 5.6 to 6.0 are considered moderately acid, while strongly acid and very strongly acidic soils have pH ranging from 5.1-5.5 to <5.0, respectively. Crops have difficulty establishing and show a decline in productivity and yield in soils with a pH below 6.0.

Calcium (Ca) is the backbone of every living organism, including plants. Although a plant’s needs for calcium can be as high as its needs for nitrogen and potassium, it is classified as a secondary nutrient. In this post, we examine the importance of calcium and the factors that can limit its availability to plants.
