Chemical phosphorus (P) fertilizers generally exhibit low utilization efficiency. The combined application of chemical and organic manure is considered an effective strategy to improve soil P availability crop yields. However, the long-term effects partially substituting fertilizer with on efficiency yield remain poorly understood. To address this, a 5-year field experiment was conducted in double-rice cropping system evaluate impact rice yield, apparent recovery (APR), availability. Our results showed that compared conventional fertilization (NPK), 20% manure, while maintaining same total N, P, K inputs (CM(P)), increased grain by 4.59% Olsen-P content 25.48%. In contrast, swine substitution reduced input (CM(-P)) sustained levels comparable NPK. Additionally, treatments CM(P) CM(-P) APR 59.91% 82.50%, respectively, activation coefficient 139.13% 171.74%. Rice were significantly positively correlated Olsen-P, suggesting manure-induced improvements promoted both APR. Overall, our study demonstrates partial particularly input, sustainable for enhancing

Effects of long-term organic fertilizer and straw on soil quality and crop yield in a rapeseed–maize rotation system

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(4), P. e0322223 - e0322223

This study aimed to pursue more sustainable agriculture in a new rapeseed–maize rotation system. We assessed the effects of organic fertilizer and straw on soil quality crop yield through 15-year field experiment: mainly applied (MM); inorganic with (MCS); (MC); only (CS); (C) as control. Compared C treatment, yields, carbon (SOC), available nitrogen (AN), phosphorus (AP), potassium (AK), porosity (SP), capacity (FC), 0.250–2.000 mm large aggregates water-stable (WA0.250-2.000) were significantly ( P <0.05) increased by fertilization treatments (MCS, MC, MM); bulk density (SBD) WA<0.053 decreased. Similarly, addition (CS MCS) also had significant nutrients, structure, yield, compared MC treatments, respectively. However, applying fertilizers (MM) no effect. The highest nutrient comprehensive evaluation value (NCEV), SP, FC, MA>2.000, WA0.053–0.250, yields observed MCS treatment. rapeseed maize 36.0% 11.8% response Pearson correlations showed that total (TN), (TK), AK, SBD, strongest correlates followed SOC, WA>2, WA0.250–2.000. suggests was best method increase improving WA>0.250, reducing SBD WA<0.053.

Organic Fertilizer with High Nutrient Levels Affected Peanut-Growing Soil Bacteria More Than Fungi at Low Doses

Agronomy, Journal Year: 2024, Volume and Issue: 14(4), P. 765 - 765

Published: April 8, 2024

The breeding of laying hens and broilers in China has increased tremendously. Wet organic fertilizer prepared from hen manure using high-temperature container fermentation preserves high levels nutrients a diverse microbial community. We applied low doses to peanuts the black soil area China’s northeastern region. Based on calculation nitrogen content, treatments were set as follows: chemical (PCF), (POF, 4500 kg·ha−1), replacement 50% with (PR, 2250 kg·ha−1). Compared plots fertilizers, use replacing fertilizers significantly peanut yields. Both did not affect activities most tested enzymes related carbon transformation absolute abundance microorganisms. However, they enhance dehydrogenase α-glucosidase. community ratio fungi/bacteria trended downward, leading high-fertility bacterial composition. enhanced species richness diversity fungal communities. Organic treatment relative Gemmatimonas Sphingomonas. Mycobacterium where replaced was lower than that treatment. PCoA results showed low-dose treatment, fertilizer, had significant impact composition
