“…3). This is consistent with the studies of others, i.e., LUC is an important cause for the high soil nutrient levels (Luz et al, 2019;Roobroeck et al, 2021;Kim et al, 2023;Mulimbi et al, 2023). The average available P and K in 0-20 cm soils Meixian in 2017 were 111 mg kg -1 and 509 mg kg -1 (Fig.…”

Land use change (LUC) is a key factor affecting nutrient budgets in agricultural soils. Comparing the long-term trajectories of nutrient budgets and changes in soils at a regional scale with contrasting LUC is critical to optimizing nutrient management and minimizing adverse environmental effects. We investigated the nutrient budgets and changes in soils in two counties in the south Loess Plateau, China, with contrasting LUCs from 1992 to 2017. Wugong County has cereals as the main crop, whereas Meixian County has the main cereal crops changed to kiwi orchards. We found that nitrogen (N), phosphorus (P), and potassium (K) inputs in two counties increased rapidly, and the nutrient outputs by crop harvests remained relatively stable. This resulted in increasing nutrient surpluses in the soils of two counties. Nutrient surplus in the orchard-dominated county was higher than that of the cereal-dominated county, and nutrient use efficiencies were contrasting. High N surplus in the orchard-dominated county resulted in high nitrate-N accumulation in deeper soil profiles of orchards. High P and K surpluses in the two counties significantly increased available P and K in 0-20 cm depth. Soil available P and K in the orchard-dominated county were significantly higher than in the cereal-dominated county, which was also significantly higher than the threshold values of available P and K contents in soils. We conclude that comprehensive measures should be taken to control nutrient surpluses, which will help to balance nutrient inputs and outputs and minimize nutrient losses in intensive horticultural crop systems.

“…In relation to the promotion of conservation agriculture, which, according to Refs. [92,93] implies agricultural practices that are respectful of soil, water, air, and the environment, 52.50% of the farmers highlighted that the government actively supported conservation agriculture. Some 20% stated the opposite, and 27.50% were undecided in their answers (see Figure 8).…”

The agricultural sector of Sinaloa is one of the most representative in Mexico. Its economic and social contributions are of great magnitude, as is its scale of production and the social impacts it generates. The objective was to study the perception of maize farmers in the municipality of Guasave on agricultural public policies and their impact on sustainable results in the sector. The methodology was quantitative-descriptive and cross-sectional. A sample of 260 farmers was analysed out of a study population of 18,650, to whom a survey was applied using the Likert scale. The internal consistency of the instrument was validated using the McDonald omega test, giving a (ω) of 0.868, considered reliable. Kendall’s Tau-c was used to find the relationship between the category and its respective subcategories. The results showed statistically significant correlations (Sig < 5%) that were greater than 0.7, so it was considered that the category “Public policies and sustainable development” showed a strong correlation with the subcategories “Governance and agricultural sustainability” and “Public policies in agriculture”. The results indicate that there is a need for greater attention to public policies, from their design to implementation. Agricultural activity has had a negative impact on a sustainable environment due to the current production methods. It is considered that to achieve significant progress in this sector, studies are needed to help detect and correct these problems and encourage greater participation of the actors in the sector in their work through training and the dissemination of sustainable practices.
