“…Figure 4F showed that the characteristic peaks of K 2 SO 4 could be found in X-ray diffraction (XRD) spectrum of product according to standard atlas in JADE, demonstrating that K 2 SO 4 was the main crystal component and humic/fulvic-like acids may possess amorphous structure. In other words, the product could be seemed as a kind of combined organic-inorganic fertilizer containing both K + and humic/fulvic-like acids 60 . The production of K 2 SO 4 was likely attributed to the reaction between PS and KOH (Eqs.…”

The demand for milk has increased globally, accompanied by an increase in waste milk. Here, we provide an artificial humification technology to recycle waste milk into an agricultural nano-fertilizer. We use KOH-activated persulfate to convert waste milk into fulvic-like acid and humic-like acid. We mix the product with attapulgite to obtain a slow-release nano fulvic-like acid fertilizer. We apply this nano-fertilizer to chickweeds growing in pots, resulting in improved yield and root elongation. These results indicate that waste milk could be recycled for agricultural purposes, however, this nano-fertilizer needs to be tested further in field experiments.

To investigate the coupling effects of biochar and nitrogen fertilizer on tomato growth, nitrogen uptake and utilization (NUU), and the soil environment, a pot experiment was conducted using 15N-tracing technology from March to July 2021 and from September 2021 to January 2022. Three biochar application rates (B0, B1, and B2; 0, 3, and 6 t/hm2, respectively) and three nitrogen levels (N1, N2, and N3; 150, 300, and 450 kg/hm2, respectively) were set up. The results show that the growth, yield, rate of 15N uptake, nitrogen derived from soil (Ndfs), total nitrogen (TN), 15N utilization, and recovery rate of tomatoes were improved under biochar application, but nitrogen derived from fertilizer (Ndff) gradually decreased. A Pearson correlation analysis showed that the 15N uptake, Ndfs, TN, rhizosphere soil organic matter, soil organic carbon, and TN were significantly positively correlated with the yield and lycopene content of tomatoes. The comprehensive benefit to the tomatoes was evaluated based on combination weighting with the help of the technique for order preference by similarity to ideal solution (TOPSIS). This indicates that the best planting mode was the B2N2 treatment, with a biochar rate of 6 t/hm2 and nitrogen levels of 300 kg/hm2, under the alternative partial root-zone irrigation.

“…Chemical fertilizers have been widely used to obtain the highest productivity in conventional agricultural systems. The application of chemical fertilizers for improving soil fertility during crop cultivation season has apparently increased crop yields to satisfy the global need for food [4]. However, the sole application of fertilizers cannot satisfy the need for food for a very long time in the future, as the long-term excessive application of chemical fertilizer, causing soil degradation, has been reported in many areas [5].…”

The Yellow River Delta is an important grain production base in China, and it is a typical Yellow River irrigated area. Chemical fertilizer overuse has seriously affected grain production safety, and understanding the fertilizer application situation is useful for scientific agronomy management. In this study, we collected the data of the N, P, K fertilizers for crop cultivation in Donging City from 2011 to 2020, and we collected 185 investigating questionnaires to gather information on the fertilizer application rate for small farmers. The results showed that the amount of total fertilizer used has decreased from the year 2015, but the macro element fertilizer rate for crop cultivation exceeded the recommended dosage. The application of compound fertilizer increased during the investigated 10 years, and its proportion in 2020 was 1.65 times higher than in 2011. For obtaining an ideal grain yield, the N and P2O5 had relative reduction rates of 67.8% and 69.6% for wheat planting. Furthermore, the relative reduction rates of N, P2O5, and K2O were 25.9%, 69.6%, and 59.7%, respectively, for maize cultivation when compared to the recommended dosage. During wheat growth, the potassium fertilizer was needed to increase the dosage, although the K element content in the soil was high. Furthermore, the medium and trace elements are all important nutrients for improving crop yield and quality which need to be studied. More scientific measurements should be conducted to match chemical fertilizer reduction to constructing healthy and sustainable agriculture in the Yellow River irrigated area.
