[Objectives]To study the activation effect of hydrochemical energy in regenerative agriculture on the nutrients of arsenic sandstone.[Methods]Starting from common environmental factors,moisture,it studied the mechanism of the release and activation of N,P,K nutrient elements in arsenic sandstone under different dry and wet environments.[Results]Water played a positive role in activating soil *** the conditions of long-term dryness and alternating dry and wet conditions,the content of total nitrogen,available phosphorus and available potassium coexisted in the 210 d of culture and the element absorption and release,but the overall trend was increasing;under long-term flooding conditions,the content of total nitrogen and available potassium showed an overall increasing trend during the 210 d of culture,but the content of available phosphorus decreased.[Conclusions]Water plays a positive effect on activating soil *** research results are expected to provide a certain reference for the application research of water in regenerative agriculture.

Developing a new agenda for increased food and climate security

引用

Frontiers of Agricultural Science and Engineering 2024年第1期11卷 35-54页

作者： William J.DAVIES Lancaster Environment Centre Lancaster UniversityLancasterLA14YQUK

In many countries, political and environmental pressures are currently combining to generate a perfect storm of circumstances that is reducing food availability, increasing food costs and thereby reducing the availability of food to many. The UK is currently considering new national food and land management policies, and attention is also being given to legislation to address diet-related health issues. Many now argue for a revolution in UK farming practices to reduce their impact on the natural environment. The UK is not alone in facing these and other challenges. Both the contribution of agriculture to greenhouse gas(GHG) emissions and the effects of climate change on food production are issues receiving worldwide *** agricultural practices can result in greater C capture, reduced GHG emissions, enhanced soil quality and enhanced biodiversity. However, it is questioned if such farming systems will be productive enough to feed a growing population with the food required for social and health benefits. To fully exploit the impact of new plant science in farmer fields, it is imperative to effectively link science to farming practices and conduct a broader conversation around the food revolution with social scientists and with the general public.

Conventional agricultural techniques have been degrading American soils nationwide since the beginnings of modern-day agriculture through practices such as soil tilling, using nitrogen synthetic fertilizers, and monocultural systems. These techniques contribute to degrading soil health, mass emissions of carbon dioxide into the atmosphere, and decreased biodiversity. regenerative agriculture techniques include the utilization of cover crops, compost, no-tillage, the integration of livestock, and crop rotation. The APS Laboratory for Sustainable agriculture focused on the effectiveness of compost by comparing the growth of lettuce in four different treatments: 100% Compost (100%C), 75% Compost 25% Miracle-Gro (75%C - 25%MG), 50% Compost 50% Miracle-Gro (50%C - 50%MG), and finally, 100% Miracle-Gro (100%MG). The lettuce seeds were kept in a growth tent for fifteen days during their period of germination before being transferred to four 1 × 1 × 0.15 m plots in the Food Forest at Florida Gulf Coast University (FGCU) for the 60-day growth period. The lettuce crops grew to full bloom and were ready for harvest. Sampling events took place every six days in which crop growth data including wet weight (g), dry weight (g), nitrogen (mg/g), chlorophyll concentration (mg/cm2), and leaf area (LA) (cm2) were collected. Statistical analysis was then conducted from the data. Based on the statistical tests conducted at the 5% significance level using R statistical software, soil treatment type was found to be significant (p = 0.0002). Soil treatment type was shown to have significantly impacted wet weight (p χ2 [3] = 3.91, p = 0.2717). 100%C and 100%MG of soil treatments produced the most successful lettuce crops. The 100%C soil treatment yielded lettuce crops with the heaviest wet weights and the largest LAs, and the 100% MG soil treatment yielded the heaviest dry weights and the highest nitrogen readings. Results demonstrate the effectiveness and feasibility of using compost as a
