Water Soluble NPK Fertilizer
NPK water soluble fertilizers are indispensable in greenhouse horticulture. Without the elements that a NPK fertilizer consists, there is no healthy growth possible for the crop.
Soluble fertilizers usually have N-P-K numbers listed on their label. The numbers listed are not always the exact percentages, they are an indication of the smallest percentage that the fertilizer contains of the listed element. The reason for this is that companies do not want their competitors to know the exact amount of nutrients they have in their product, so they list the lowest levels their product might contain to thwart any copying of their secret growing compounds. The N is for nitrogen, the P is for phosphorus and the K is for potassium or potash. Of the 16(12 of which are contained in water soluble fertlizers) known elements necessary for plant life, N-P-K, are the three that are of the most importance and always listed on water soluble fertilizers, in that order(except Eco-Grow, which lists N-K-P). Following N-P-K, calcium(Ca) and magnesium(Mg) are the two, second most important nutrients listed on the label. The rest, iron(Fe), sulfur(S), manganese(Mn), boron(B), molybdenum(Mb), zinc(Zn) and copper(Cu) are trace elements or micro-nutrients.
The abbreviation NPK stands for the three elements nitrogen (N), phosphorus (P) and potassium (K). Each element has a different function and effect on the plant and is badly needed in a healthy growth of the crop. Depending on the crop, growth phase and the desired result, a suitable NPK ratio is chosen.
NPK water soluble fertilizers offer complete fertilization, to which trace elements are often added. The fertilization with an NPK water soluble fertilizer can be made in the B-barge. Each element of the fertilizer has its own effect:
Nitrogen (N): mainly causes cell elongation in the growth phase of the plant. The leaves and stem of the crop also get a nice green colour. Each plant needs a certain amount of nitrogen. If the plant is offered too little nitrogen, various deficiency symptoms can result. A good dose of nitrogen is therefore very important.
Phosphorus (P): promotes root development. Better roots make it easier for the plant to absorb water and minerals. As with nitrogen, it is important to ensure a good dosage of phosphorus to prevent deficiency symptoms.
Potassium (K): helps the plant to maintain its moisture balance by supporting the opening and closing of its stomata. A good amount of potassium in the crop provides a sturdy plant, with better resistance to fungi. Always keep an eye on the unwanted symptoms of potassium deficiency in the crop.
The fertilizer with the proper NPK proportion depends on the crop, growth phase and desired result.
