Organic wheat production systems have lower yields compared with intensive conventional and often do not achieve the grain protein content quality thresholds set by millers bakers. In contrast, organic methods were reported to result in higher concentrations of nutritionally desirable micronutrients toxic metal Cd wholegrain flour. However, although N-availability variety characteristics are known affect both gain bread-making quality, exact reasons for yield gap differences processing nutritional between spring UK poorly understood. The overall aim this study was therefore determine what extent changes choice fertilization regimes may reduce improve without affecting production. To aim, we crop health, yield, processing, parameters produced using (i) six contrasting varieties grown a standard regime (ii) one widely used farmers (Paragon) nine different (iii) three sites/farms pedoclimatic conditions.

Although fertilizer input type level affected performance, smaller than those observed five varieties, improvements breeding/selection greater potential increasing sector practices. Overall, results suggest it feasible breed/select combine protein, vitamin E, low (Cd, Pb) These findings support hypothesis contributed products previous studies.

Soil microbial species diversity and distribution of communities are vital for soil crop health, nutrient cycling, availability, subsequent plant growth. These dynamics highly influenced altered by various management practices, inputs, agricultural techniques. In the present study, effects chemical organic practices on community structure were examined compared using amplicon sequencing 16S ITS regions. Two contrasting samples selected from each fields at International Rice Research Institute-South Asia Regional Centre (IRRI-SARC) in Varanasi: one field followed conventional fertilizer while other implemented natural farming including tillage, on-farm residue management, water management. analyzed bacterial fungal diversity. Our findings showed that two differently managed soils exhibited distinct compositions, with organically exhibiting a higher decomposer bacteria fungi, showing 40 unique elements 19 chemically soil. Natural also demonstrated relative abundance phyla. results emphasize significance sustainable techniques, suggesting inputs can increase richness. The functional roles these ecosystems their potential impact yield cycling warrant further study.

Agriculture is undergoing an agroecological transition characterized by adopting new practices to reduce chemical fertilizer inputs. In this context, digestates are emerging as sustainable substitutes for mineral fertilizers. However, large-scale application of in agricultural fields requires rigorous studies evaluate their long-term effects on soil microbial communities, which crucial ecosystem functioning and resilience. This study presents provides a comparative analysis field conditions fertilization strategies combining annual applications raw digestate with biennial different organic waste products (OWPs)-biowaste compost (BIO), farmyard manure (FYM), urban sewage sludge (SLU)-and compares them combinations the same OWPs The cumulative repeated OWP applications, paired two nitrogen sources-organic (digestate) (mineral fertilizer)-were assessed through physicochemical analyses. We hypothesized that combined effect varied according N-supply sources also depended type applied.

Abstract Intensive agriculture has increased global food production, but also impaired ecosystem services and soil biodiversity. Organic fertilization, essential to organic integrated farming, can provide numerous benefits for quality compromise the environment by polluting soils producing greenhouse gases through animal husbandry. The need reduced stocking density is inevitably accompanied lower FYM inputs, little research available on impact of these effects microbiome. We collected samples from winter wheat plots a 42-year-old long-term trial comparing different farming systems receiving farmyard manure at two intensities measured parameters microbial community diversity DNA metabarcoding. High-input corresponding 1.4 livestock units (LU) improved soil’s nutritional status biomass respiration when compared low-input 0.7 LU. Bacterial fungal α-diversity was largely unaffected fertilization intensity, whereas their structure changed consistently, an increase in bacterial copiotroph-to-oligotroph ratio high-input more copiotrophic indicator OTUs associated with high than low-input. This study shows that nutrient availability under selects oligotrophic microbes efficiently obtaining nutrients various carbon sources; potentially beneficial trait considering future agroecosystems.

Soil organic matter (SOM) plays a vital role for soil quality, sustainable food production and climate change mitigation. It is common knowledge that SOM consists of different pools with varying qualities, quantities, turnover times. However, it still poorly understood how mineral fertilization affects the formation stabilization mineral-associated (MAOM) long can remain there. Here, we report on long-term effects farming systems stability fine silt clay-sized MAOM fraction (<6.3 μm) Haplic Luvisol (0–20 cm) in DOK trial (Switzerland).

The global population surge has escalated the demand for food production. While conventional farming meets consumer demands, it often compromises quality and safety. This method of agriculture significant adverse effects on health environment, relying heavily chemical fertilizers, costly seeds, machinery. Conventional contributes to environmental degradation, food-borne illnesses, soil infertility. In response these issues, organic gained prominence worldwide. rising products is driven by their nutritional benefits. Numerous studies have explored advantages disadvantages various methods, comparing practices. paper reviews emerging impacts environment climate change examines differences preferences vegetables produced two methods.

Abstract Organic matter is a vital component of soils and decisive for soil health sustainable food production. Agricultural use often decreases organic stocks climate change may aggravate the situation, putting security ecosystem functioning at risk. Bio‐based fertilizers (BBFs, most waste or residue‐derived) are part future circular economies focussing on closed nutrient cycles in production agriculture. It unclear if BBFs have positive effects carbon (SOC) because studies were so far mostly focussed plant nutrition ran mainly as short‐term pot experiments. We filtered, extended reclassified comprehensive meta‐analysis Chen et al.
