“…In our results, the decrease in crop yield over the years in N0 and N100 treatments was consistent with previous studies [50,51]. Cai et al [52] also reported that crop yield was not increased after 12 years of inorganic N application due to decreasing in soil pH. Long-term application of inorganic N fertilizer decreased NRE due to reducing soil pH and hardening soil structure [53].…”

“…Furthermore, estimated C input and N uptake and AN were mainly factors influencing crop yield ( Figure 6). In a previous study, Cai et al [52] observed that manure was main influencing factor of crop yield. Therefore, substitution of inorganic N fertilizer by GM not only increased NRE and N uptake but also increased soil C content more than sole N fertilizer treatment that helped to reduce the yield variability and increased long-term crop yield stability.…”

A long-term field experiment was carried out (since 2008) for evaluating the effects of different substitution rates of inorganic nitrogen (N) fertilizer by green manure (GM) on yield stability and N balance under double rice cropping system. Treatments included, (1) N0 (no N fertilizer and no green manure); (2) N100 (recommended rate of N fertilizer and no green manure); (3) N100-M (recommended rate of N fertilizer and green manure); (4) N80-M (80% of recommended N fertilizer and green manure); (5) N60-M (60% of recommended N fertilizer and green manure); and (6) M (green manure without N fertilization). Results showed that, among all treatments, annual crop yield under N80-M treatment was highest. Crop yield did not show significant differences between N100-M and N80-M treatments. Substitution of different N fertilizer rates by GM reduced the yield variability index. Compared to the N0 treatment, yield variability index of early rice under N100-M, N80-M, and N60-M treatments was decreased by 11%, 26%, and 36%, respectively. Compared to the N0 treatment, yield variability index of late rice was decreased by 12%, 38%, 49%, 47%, and 24% under the N100, N100-M, N80-M, N60-M, and M treatments, respectively. During period of 2009–2013 and 2014–2018, nitrogen recovery efficiency (NRE) was highest under N80-M treatment and N balance was highest under N100 treatment. NRE of all treatments with GM was increased over the time from 2009–2013 to 2014–2018. All treatments with GM showed increasing trend of SOC over the years. Substitution of N fertilizer by GM also increased C inputs and soil C:N ratio compared to the N100 and N0 treatments. Boosted regression model indicated that C input, N uptake and AN were most influencing factors of crop yield. Thus, we concluded that N fertilization rates should be reduced by 20% under GM rotation to attain high yield stability of double rice cropping system through increasing NRE and C inputs.

“…As the estimated amount of nutrients available directly from the FYM to the wheat was relatively low in our case (5%), we incline to the fact that the positive effect of manure consisted in the direct effect of released nutrients, which were mostly utilized by pre-crops and partially by wheat, and also in influencing the microbial part, nutrients turnover, and organic matter pool in soil. As we didnot perform the PLFA or other methods for evaluation of soil microbial activity, we cannot confirm these suggestions directly, but are in an agreement with the results of other researchers [16,17].…”

Farmers must adapt to the changes brought about by the changing climate and market requirements. These adaptations are associated with fertilization—the availability of organic manures and mineral fertilizers and crop rotations. What is the effect of organic manures on wheat and soil? Is it necessary to apply mineral phosphorus P and potassium (K) fertilizers to the wheat? These questions are frequently asked in workshops in different growing areas. To provide a relevant answer on this issue, we evaluated how farmyard manure (FYM), mineral nitrogen (N) applied without phosphorus (P) and potassium (K) fertilizers, and application of NPK affected grain yield, grain quality, and soil properties under different soil-climate conditions (Ivanovice—Chernozem, Caslav—Phaeozem, Lukavec—Cambisol) between 2015 and 2018. The FYM significantly increased grain yield even after three years since being applied and incorporated into the soil in all localities, but its application didnot affect grain quality. In the soil, the FYM significantly increased total nitrogen Nt, P, and K content in all localities and oxidable carbon Cox content in two localities. Mineral nitrogen significantly affected grain yield and quality and increased concentrations of soil N and C, but decreased pH in Caslav. Application of mineral P and K wasnot connected with a positive effect on grain yield and quality, but increased the concentration of these elements in the soil, preventing depletion of these elements from the soil. Maximal yields were recorded when 70–98 kg N ha−1 was applied in Ivanovice, 55–72 kg N ha−1 in Caslav, and 155 kg N ha−1 in Lukavec.

“…33% of farmers in Grande-Terre and 11% of farmers in Basse-Terre applied mineral fertilizers. Agricultural production has increased, since the 1950s, due to the large input of mineral fertilizers [45]. However, the intensive use of mineral fertilizers has a negative impact on soil fertility (soil acidification) and yield production [46].…”

Intensive agriculture practices have an important impact on soil biota, which can affect dramatically soil quality. In order to limit this impact, alternative agricultural practices are more and more applied. However, these practices are still in progress and thus, it is necessary to investigate their impact on soil activity. In this context, we studied the impact of agricultural practices (intensive and agroecological) in vegetable cropping systems in Guadeloupe. The first aim of this study was to identify practices developed in vegetable cropping systems and explain their level of eco-agriculture. We conducted a survey on the whole territory which gave us a better understanding of vegetable cropping systems in Guadeloupe. We selected a representative subset of 18 farms located on vertisols. The second aim of the study was to establish a typology of cropping practices in these vegetable cropping systems in vertisol. We performed a PCA and a HCA on the 18 farms. These methods allowed us to build a typology in which farms were distributed between two types. In type A, farmers are using intensive agricultural practices while in type B, farmers are using alternative agroecological farming practices. Then, we collected soil fauna, during the rainy season in type A and type B farms in order to demonstrate the relationship between cropping systems and the quality of soils proxied by biological indicators. We hypothesized that the use of synthetic fertilizers and herbicides in intensive agriculture affected soil fauna activity. The results showed no significant difference between soil fauna abundance in both types. However, the taxonomic richness and the abundance of litter transformers were higher in type B. Taxonomic richness and soil fauna functional diversity thus strongly depend on agricultural practices in vegetables cropping systems in Guadeloupe.
