Why the need for periodical agrochemical soil analysis?
One of the important natural ingredients that surround us and that are vital for life support of humankind, is the soil environment for many organisms, the food source for the plants. Agriculture, with the purpose of growing products, as well as feed for livestock production is the basis of our existence. State of productive soil is required to be the object of attention of land owners and land users. Therefore, the agrochemical soil survey should be conducted on a regular basis.
the Soil is closely interlinked with other natural elements (atmosphere, hydrosphere, and underlying rocks, the biosphere). Participating in a constant cycle of the substance, it may change its fertile properties. Small and practically unnoticeable changes can affect the yield of agricultural crops. The purpose of agrochemical soil analysis – to detect such changes, to justify methods of application of mineral and organic fertilizers, the use of other agricultural technologies to maintain optimal for agriculture soil characteristics.
Than the ground?
the Soil is a multicomponent education, consisting of solid, liquid and gaseous components, besides rich by living organisms.
- the Liquid part is water and soluble in organic and inorganic compounds (soil solution).
- Gas part is air, which fills the structural voids (where there is no water).
- Living organisms is represented by a variety of bacteria (up to several million per one gram of soil material). They turn dead organic matter, structure.
the Hard part is presented gruntovalnoy rock (it is also called the parent). In addition to the minerals of the parent rock, the soil is humus (organic matter that was once in the organisms of animals or plants). It is the humus mainly determined by the soil fertility – the ability to ensure the growth of the plants for nutrients.
Features that are considered in the agrochemical examination of the soil
In the course of the agrochemical analysis of the soil may be a wide variety its characteristics, which are divided into such groups of agrochemical parameters:
- the Basic parameters. They include pH value (pH), hydrolytic soil acidity, the total content of organic matter, granulometric composition, amount of absorbed bases.
- Content of macro elements (nitrate, nitrite, ammonium nitrogen, potassium, sodium, calcium, phosphorus).
- the Content of trace elements important for life processes of plants (zinc, cobalt, molybdenum, Nickel, copper, manganese).
- the Content of toxic impurities in the soil (oil and oil products, harmful metals and salts, benzo (a) pyrene).
- characteristics of bacterial contamination of the land (presence and number of Escherichia coli, enterococci, Salmonella, and other pathogens).
Timely agrochemical analysis of the soil is of great importance. Without it difficult to make informed agricultural decisions that contribute to raising productivity, increasing efficiency of land use. Comprehensive or narrowly focused agrochemical survey of land can be charged, signing the corresponding agreement, the company "Guild Engineering".
