Abstract:

Finding ways to improve soil health while minimizing environmental damage caused by water erosion is crucial. This research evaluates the effect of the dosage in organic fertilizers impacting the surface runoff rate and erosive wash. This study focuses on the analysis of organic fertilisers, specifically manure, digestate, and compost. The study was carried out in the vicinity of Nesperská Lhota Village, located in the Czech Republic. The correlation between soil carbon content and fertilisation with organic fertilisers, as well as other metrics and technologies, is indeed influenced. The aforementioned concepts can be directly associated with the measurements conducted at the Nesperská Lhota site. Based on the assessment of the measurements, it is evident that the manure yielded the most favourable results. The digestate and compost versions exhibited a little unexpected outcome when administered at a dosage of 200 t.ha-1. It is thought that the digestate has partially clogged the soil pores, hence decreasing the soil's capacity to absorb water. Compost had a lower water infiltration rate compared to different types of manure. This phenomenon can likely be attributed to the lack of bigger macroparticles. The significance of this effort will progressively escalate as time progresses. The continuously growing population necessitates a greater quantity of food, while simultaneously acknowledging that land is one of the few resources. Undoubtedly, the proper utilisation of organic fertilisers is a prominent future trend in agriculture.
