  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Application of two vermicomposts on a Rice crop: Effects on soil biological properties and rice quality and yield

    Vermicomposts have been considered as a soil additive to reduce the use of mineral fertilizers because they provide required nutrients, increase cation exchange capacity, and improve water-holding capacity. However, the effect of each vermicompost on soil properties and crop yield depends on its chemical composition. The main objective of this work was to study the effect of incorporating two ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...
