Cropland acidification in China has decreased crop yields and accelerated cadmium accumulation in edible crops. Enhancing manure recycling effectively mitigates soil acidification but increases the risks for cadmium accumulation due to elevated cadmium contents in manure. Here we coupled a dynamic cadmium model with the soil acidification model VSD+ to assess the spatial-temporal impacts of nutrient management on soil acidification and cadmium dynamics in a typical Chinese paddy rice system. Enhancing manure recycling decreased soil acidification and almost completely reduced mineral phosphorus fertilizer use, but accelerated soil cadmium accumulation through increased manure cadmium inputs and reduced cadmium leaching. Raising soil pH without lowering cadmium inputs reduced rice cadmium contents in the short to medium term, but continued soil cadmium accumulation offset these benefits in the long term. Under current cadmium deposition levels, only around 20% of the manure can be safely recycled without exceeding cadmium safety thresholds, which is lower than the current manure recycling ratio of 30%. When cadmium deposition is minimized, the manure recycling ratio can increase up to 85%. To enhance manure recycling sustainably, a lowering of cadmium content in manure and cadmium deposition is required.

Grain zinc (Zn), iron (Fe) and protein concentrations have declined in wheat cultivars released since the 1960s. Here we conducted a meta-analysis of field studies to provide a global synthesis of how genetic, environmental and agronomic factors influence grain Zn, Fe and protein concentrations. The probability of achieving the Zn target (38 mg kg-1) was 38.9% across bread wheat and 42.7% of durum wheat grain samples, but only 28.5% of released bread wheat cultivars met this target. The probability of achieving the Zn target was 44.7% with Zn-biofortified cultivars but only 24% with non-fortified cultivars. The likelihood of achieving the Fe target (59 mg kg-1) was <8% across bread and durum wheat grain samples. Relative to nitrogen, phosphorus and potassium fertilizers, co-application of Zn and Fe increased grain Zn, Fe and protein concentrations by 27%, 41% and 25%, respectively. Combining agronomic and genetic biofortification is essential for improving grain nutrient concentrations and addressing micronutrient deficiencies.

Manure recycling can ameliorate pollution and fertilizer demand, but varying assumptions about recoverable manure nutrients and crop requirements complicate understanding of manure recycling potential. Using nitrogen (N) in the contiguous USA as a case study, we applied methods from six studies to compare manure N balance estimates (recoverable manure minus crop demand). We then developed a framework to assess both current and future potentials of manure recycling. The current balance in the USA is -13.3 ± 1.1 TgN yr-1, reflecting large crop demand currently met with synthetic fertilizer. Improved adoption of current manure management technologies could decrease this deficit by 5%, while future technologies could enable another 21% reduction. However, new manure N application should be reduced by 33-36% to avoid phosphorous (P) overapplication. Improved crop N efficiency could decrease the deficit by 27%. Applying this framework at county level demonstrates variable regional opportunities to improve manure recycling.
