Hydroponic nutrients are more crucial in application than in conventional agricultural system. Plants are more sensitive to variations in nutrient concentrations and ratio’s so it is crucial to monitor the nutrient mix and levels on a daily basis
Calcium and Boron have a close relationship in the plant. Their absolute concentrations and the relative ratio between the two affects how much of each...
The concentration of manganese (Mn) can vary significantly in re-circulating nutrient solutions. Crop uptake of manganese cannot be explained to this high variation and the...
The ammonium/nitrate ratio in the nutrient solution is important since it can have a significant effect on the quality and total yields of the tomato...
It is often quite difficult to identify a deficiency or toxicity symptom in the field because they never really occur as a single element deficiency...
Tomato fertigation is a complex subject in hydroponics. It is climate sensitive and everybody has an opinion of what works. The point is, tomatoes are...
Fertigation of peppers is sometimes more of an art than science since plant requirements change as the weather/climate change. Learn how to read your plants...
Most automated systems installed in closed hydroponic systems use injectors rather than proportioners. A simplified diagram of where to install such a system is provided...
Fertilizer solubility is one of the key elements in making hydroponic nutrient stock solutions. If you know the fertilizer solubility, you can make optimum stock...
Not all fertilizers are pure. Some have impurities, such as clay, silt and sand particles, also called “carriers”, that do not provide any nutrients to...
Liquid fertilizers are treated slightly different than granular fertilizers. They do not have impurities, but their density or specific gravity need to be taken into...
The first question would be where to start and with what element. The following procedure should be followed. Always start with the element phosphorus and...
