Long-term effects of optimized fertilization, tillage and crop rotation on soil fertility, crop yield and economic profit on the Loess Plateau

Farmers' adoption of agriculture green production technologies: perceived value or policy-driven?

“…STFT is based on soil nutrients and fertilizer demand for crop growth, targeted fertilization on demand. Studies found that STFR can reduce the misuse of chemical fertilizers and also improve grain output and soil fertility [ [55] , [56] , [57] ]. This means that technology adoption can increase farm income and reduce costly inputs.…”

Can a Crop Rotation and Fallow System Reduce the Carbon Emission Intensity of Agriculture?

“…I t is the nominal fixed asset formation, P is the fixed asset investment value index, δ t is the depreciation rate, which is taken as 9.6 percent using the LSDV method to estimate Equations ( 4), ( 5) and (7) are brought in to obtain τ. τ > 0 represents the under-allocation of resources and vice versa for over-allocation. This paper further uses a coupled synergy model to measure the composite index of resource mismatch as follows:…”

“…Given the differences in production between plantation and livestock, this paper divides the plantation and livestock zones for heterogeneity analysis using the 400 mm isoprecipitation line as the boundary. Columns (7) and ( 8) of Table 7 show that the estimated coefficients for plantation and livestock zones are significant at the 1% and 5% levels, respectively, suggesting that the CRFS policy reduces the intensity of agricultural carbon emissions in both plantation and livestock zones, and it is more effective in plantation zones than in livestock zones. The possible economic explanation is that the plantation and livestock zones have upgraded their traditional agricultural production facilities through digitalisation, which promotes the precise management of crop growth and livestock rearing and reduces chemical inputs and energy consumption.…”

“…Fallowing avoids the overconsumption of agricultural labour and promotes the recovery of the physical quality of the labour force. The purpose of crop rotation is to regulate the physicochemical properties of soil and improve soil ecology to maintain soil fertility [7]. Crop rotation can not only alleviate the over-absorption of chemical elements but also increase soil chemical elements through the biochemical function of plants, so as to achieve calm soil physicochemical properties [8] and thus curb the intensity of agricultural carbon emissions.…”

“…The resource mismatch index mainly involves agricultural capital resource mismatch and agricultural labour mismatch. Referring toWang et al (2023)…”
