Overview of Organic Fertilizers

Ensuring balanced and adequate nutrition for the rapidly growing world population is only

possible by increasing agricultural production and productivity. Increasing productivity in agricultural

production is possible through the use of quality seeds, control of diseases and pests, irrigation, fertilization

and sustainable and efficient use of natural resources such as soil. It is important to use soil, which is a

determining and exhaustible resource in agricultural production, in a sustainable manner. Fertilizers, one

of the important inputs in agricultural production, determine yield and quality. Today, it is known that soil

sustainability and human health are negatively affected by some reasons. Among these, unconscious and

excessive use of inorganic (chemical) fertilizers to obtain high yields and continuous use of inorganic

fertilizers cause water and soil pollution. Therefore, considering the negative effects of chemical fertilizers

today, organic fertilizers have become very important as an alternative to chemical fertilizers used

worldwide to ensure agricultural sustainability. Organic fertilizers stand out with the nutrients they contain.

Organic fertilizers containing nitrogen (N), phosphorus (P), potassium (K) and other nutrients at different

rates according to the source of organic matter, meet the need for plant nutrients, which have an important

place in plant production, as well as improving the physical, chemical and biological properties of the soil.

Organic fertilizers commonly used in our country are barn and poultry manure, green manure and composts.
