Literature review: Soil Ecosystem problem for Agriculture
The “Ten Problems for Agriculture in the 2020s” booklet identifies ten relevant areas from very recent contributions put forward at academic level in the form of journal articles, conference proceedings and students theses. Ten freely accessible internet references have been selected for each area and direct links are provided at the end of each chapter for own consultation. Our selected references do not intend to mirror ranking indexes nor establish novel classifications. On the contrary, they are meant to represent peer-reviewed, diverse and scientifically-sound case studies for vertical dissemination aimed at non-specialist readers. They will also be able to scoop even more references through the bibliography that is reported at the end of each selected reference.
Without further ado, these are the ten problems that we are going to introduce in this booklet:
- climate change,
- precision agriculture,
- crop planning,
- soil ecosystem,
- developing countries,
- biological control.
Each problem has its own dedicated chapter made of an introductory section, a short presentation of the ten selected references and a conclusions section.
The final chapter of this booklet will report the conclusions from each chapter again in order to provide a complete executive summary.
5 Soil Ecosystem
THE PROBLEM – Many soil ecosystems locally, pretty much everywhere on planet Earth, are under stress because of intensive agriculture practices aimed at output maximization, aggressive environmental conditions caused by climate change, pollution from deposition and plastics, natural degradation and erosion, unhealthy management. The United Nations are therefore promoting a sustainable soil ecosystem framework to help communities get increasing value from farming while preserving natural resources.

CONCLUSIONS — Ranking soil factors can be complex as there are many stakeholders at different levels with different priorities. For example, soil erosion is a geomorphological and, at the same time, a major land degradation process. In addition, there is a considerable potential in the expanded area of microorganisms to replace synthetic biological chemistry. Atmospheric deposition flow (wet, dry, and total) serves as one input of addends to soils; however, deposition varies spatially across regions. From an economic perspective, though, the net present value to society of implementing soil-friendly measures are substantial, but negative for farmers in many regions. Heavy metal contaminants of environment pose detrimental effect on human health and are listed as priority pollutants. There is also some statistical and empirical evidence of the impact of land pollution on agriculture and agriculture as pollutant. Soil databases for Ecosystem Services and Sustainable Development Goals are needed at local level and ‘soil security’ has gained support among soil advocates but still lacks traction in the political arena. For example, soil pollution with plastic is estimated to be 4 to 23 times higher than water pollution with plastics, with a negative impact on soil biota. While a lot is known about viruses in the soil, the potential presence and behavior of COVID-19 in the soil is not known.
