    Alternatives for the sustainable management of soil fertilization and plant nutrition 2022

    From the end of 2021, and so far in 2022, the the world faces a shortage of fertilizers, driven by a rise in prices of approximately 78% in this lapse. Additionally, fertilizers have ceased to be available in the market, due to the fact that numerous production plants facing negative margins stopped production, due to the increase in the price of energy, among other reasons. Consequently, it it is expected that the reduction of fertilizer applications decrease the yield and quality of the production of foods. All practices that promote an increase in matter organic growth and increased soil biodiversity will improve its fertility and ability to supply nutrients to plants. However, it is important to maintain a balance between physical, chemical and biological properties of the soil. This document briefly summarizes the alternatives compiled to date by the Community of Practice of soils (CoP-Soils) for Latin America and the Caribbean, and other additional measures implemented in the region to deal with this situation.

    Of the essential material needs of humankind, the basic requirement is for an adequate supply of air, water and food. People have free access to the air they breathe. However, access to drinking-water and food, while easily obtained for some, is difficult for many. In addition to being physically available, these materials should also be of acceptable quality and continuously so. Hunger and diseases have affected humankind since the dawn of history. Throughout time, there have been p eriods of famine leading to suffering and starvation, making the fight against hunger and the diseases caused by malnutrition a permanent challenge. For many centuries until about 1800, the average grain yield was about 800 kg/ha, providing food only for a few people. The main problems were the low fertility of most soils (mainly caused by the depletion of nutrients) and the great yield losses from crop diseases and pests.
