It is common knowledge that to reap good harvest, fertilizers are needed, mineral ones in particular, i.e. substances that contain nutrition elements for plants in the form of various inorganic combinations. Some organic combinations are also referred to as mineral fertilizers, e.g., urea and its derivatives.
The value of mineral fertilizers is in their fast action, and apart from organic ones, these fertilizers are used by plants immediately, omitting the phases of decomposition and complex metabolic process. There exist two large classes of mineral fertilizers, simple and complex ones:
- simple mineral fertilizers – contain one chemical element in their composition, which is needed for plant nutrition. Depending on this element, simple mineral fertilizers can be further divided into nitrogen, potash, and phosphorous fertilizers;
Complex mineral fertilizers contain several efficient chemical elements. They are obtained by chemical reaction between initial components.
