soil health

 

Soil health has been defined as: “The ability of soil to function as a living system. Healthy soil maintains a variety of soil biota that helps control plant diseases, insect pests and weeds, forms beneficial symbiotic unions with plant roots, recycles essential plant nutrients, and improves soil structure with positive results for the soil’s ability to conserve water and nutrients. In the end, production improves. To this definition, an ecosystem perspective could be added: healthy soils do not pollute their environment, on the contrary, it is contribute to mitigating the effects of climate change by maintaining or increasing their carbon content.

A major requirement for ecologically sustainable production is healthy soil, creating a suitable environment in the root zone that optimizes the activity of plants and animals in the soil and Improve root performance to reach the optimum limit. Roots can absorb plant nutrients and water and interact with a range of soil microorganisms that benefit soil health and crop performance.

Human and the environment are seen as one system with a primary objective that seeks to develop the health and production aspect of independent life communities, which include soil, plants, animals and humans. To achieve this goal, the means and activities of farm management should be carefully selected with the aim of repairing the ecological balance of the field and preserving it, and thus the surrounding environment, in order to protect the entire ecosystem of the planet. The motto (Feed the soil, not the plant) is a basic principle in environmentally good soil management activities. These activities include following the appropriate agricultural cycle, intercropping, using green manure, plant residues and farm animal waste, correct plowing methods and rational applications of mineral nutrients.

Soil health is the state of soil that meets its set of ecosystem functions in proportion to its environment. In other term, soil health arises from the favorable interactions of all soil components (living and nonliving) belonging together, as in the case of microorganisms, plants and animals. Soils can be healthy in terms of ecosystem functioning but do not necessarily directly serve crop production or human nutrition. The basic principle in using the term “soil health” is that soil is not just a lifeless, inert growth medium, which modern intensive agriculture tends to represent. It is a living, dynamic and ever-changing whole environment. It turns out that highly fertile soils from the point of view of crop productivity are also vital from a biological point of view. Soil microbial biomass is now known to be large in temperate grassland soils. Some microbiologists now believe that 80% of soil nutrient functions are controlled primarily by microbes. Using the human health analogy, healthy soils can be classified as having biological, chemical, and physical properties; It is not diseased, i.e. not degraded, and is resistant to deterioration of the kind that will maintain this ability in the future.

Soils will have different standards of health depending on the "inherited" traits and geographical conditions of the soil. Among the factors that determine the health of the soil wide productivity, diversity of life, absorption, storage and recycling, no damage or loss of basic components. Which results in extensive vegetation cover, little leakage of nutrients from the ecosystem, high carbon levels, high biological and agricultural productivity, no accumulation of pollutants and thus unhealthy soil is the simple opposite of the above.
