Benefits of Circular Agriculture for Cropping Systems and Soil Fertility in Oases


Circular agriculture is an efficient method for the administration of soil natural inputs that improves soil fertility and cropping system sustainability. We developed a cropping system typology and assessed results of crop rotation, natural fertilization, and crop residue administration on soil fertility properties. Farmers in Drâa-Tafilalet oases in Morocco have been surveyed, and soil was sampled and analyzed. In the most typical cropping programs (Type I), date palms have been related to cereals, forages, and perennial crops. Type II cropping programs referred to a monocropped date palm of just one cultivar. In Type III, date palm was related to different crops on half of the utilized agricultural space and monocropped on the opposite half. In all cropping programs, imply soil natural matter (SOM) content material was lower than 1.5% and the SOM:clay ratio was lower than 12%, which elevated the soil degradation danger. Livestock was mixed with crops in Type I and III cropping programs and produced 19.4 and 24.2 t of manure per farm per 12 months, respectively. Type I and II cropping programs produced yearly 0.98 and 2.1 t.ha−1 of dry palms, respectively. Recycling these natural waste merchandise stays a promising choice that might produce natural inputs and offset the present lack of manure.
