The Effect of Different Organic Fertilizers on Yield and Soil and Crop Nutrient Concentrations

At present, organic fertilizers are not widely used in intensive arable agriculture, and not much is known about their effects on crop nutrition. In a field experiment at Rothamsted, UK, anaerobic digestate (AD), compost, farmyard manure (FYM), straw, and mixes of amendment + straw, were applied at: 1, 1.75, 2.5 or 3.5 t carbon ha−1, with all plots receiving the same input of mineral fertilizer. After five seasons of application, plots receiving non-straw amendments had greater straw and grain yield of 28% and 18% respectively, and plots receiving the highest amendment rate had a 37% higher straw and 23% higher grain yield, compared to control plots. Whereas, the straw-only amendment did not increase yield compared to the control. The concentrations of secondary and micro nutrients in the crop, particularly P, Ca, and S in the straw, and P and Fe in the grain, were significantly greater in the crop receiving non-straw amendment compared to the control. Interestingly K, Fe, and Zn were greater in the crop straw treated with the straw-only amendment. Therefore ‘biomass dilution’ of secondary and micro nutrients did not occur in the higher-yielding amended plots after five seasons, and organic fertilizers would improve the quality of high-yielding, intensively produced crops. The study also demonstrates that portable x-ray fluorescence (pXRF) could be a reliable, cost-effective tool for screening potential organic fertilizers.

“…It is known that sparingly-soluble PR cannot be utilized by most plants even under pH at 4.9−5.5. 36,37 Our findings of greater DOC and acid phosphatase activity highlight the importance of root exudates in PR-induced plant growth and As accumulation in P. vittata. 41 To optimize P utilization by crop plants, further studies are warranted to identify unique root exudations and elucidate the mechanisms governing their synthesis in P. vittata roots as well as their secretion to the rhizosphere.…”

“…For most plants, PR is insufficient to support their growth, even under pH values at 4.9−5.5. 36,37 For example, nonhyperaccumulator P. ensiformis fails to acquire sufficient PR-P under P-free hydroponics, whereas As-hyperaccumulator P. vittata yields greater biomass probably due to its effective uptake of P and Ca from PR. 16 Likewise, in this study, P. vittata grew better under both As and As+PR treatments (Figure 1A).…”

Sparingly-soluble phosphate rock (PR), a raw material for P-fertilizer production, can be effectively utilized by the As-hyperaccumulator Pteris vittata but not most plants. In this study, we investigated the associated mechanisms by measuring dissolved organic carbon (DOC) and acid phosphatase in the rhizosphere, and nutrient uptake and gene expression related to the As metabolism in P. vittata. The plants were grown in a soil containing 200 mg kg −1 As and/or 1.5% PR for 30 days. Compared to the As treatment, the P. vittata biomass was increased by 33% to 4.6 g plant −1 in the As+PR treatment, corresponding to 27% decrease in its frond oxidative stress as measured by malondialdehyde. Due to PR-enhanced DOC production in the rhizosphere, the Ca, P, and As contents in P. vittata fronds were increased by 17% to 9.7 g kg −1 , 29% to 5.0 g kg −1 , and 57% to 1045 mg kg −1 in the As+PR treatment, thereby supporting its better growth. Besides, PR-induced rhizosphere pH increase from 5.0 to 6.9 promoted greater P uptake by P. vittata probably via upregulating low-affinity P transporters PvPTB1;1/1;2 by 3.7−4.1 folds. Consequently, 29% lower available-P induced the 3.3-fold upregulation of high-affinity P transporter PvPht1;3 in the As+PR treatment, which was probably responsible for the 58% decrease in available-As content in the rhizosphere. Consistent with the enhanced As translocation and sequestration, arsenite antiporters PvACR3/3;3 were upregulated by 1.8−4.4 folds in the As+PR than As treatment. In short, sparingly-soluble PR enhanced the Ca, P, and As availability in P. vittata rhizosphere and improved their uptake via upregulating genes related to As metabolism, suggesting its potential application for improving phytoremediation in As-contaminated soils.

“…Os valores de atividade microbiana observados podem ser considerados benéficos para os sistemas estudados, uma vez que maior decomposição de resíduo orgânico se refere à maior disponibilidade de nutrientes às plantas (Medeiros et al, 2019) e estímulo à atividade de outros organismos no solo (Amorim et al, 2020, Balota, 2018. Dessa forma, tem-se que a camada superficial do solo, beneficiada pelo aporte de biomassa da bananeira, pode ter favorecido as condições de temperatura interna, umidade e aeração e, consequentemente, propiciaram ambientes protegidos consoantes ao desenvolvimento da população microbiana e sua atividade.…”

O objetivo foi avaliar a qualidade do solo em função dos diferentes sistemas de produção orgânico e convencional de banana mediante análise integrada dos atributos físicos, químicos e microbiológicos, tendo como referência uma área de mata nativa. As amostras deformadas e indeformadas foram coletadas na profundidade de 0 a 20 cm, no município de Gonçalves (MG) e submetidas às análises físicas (textura, densidade do solo, densidade de partículas, porosidade total, diâmetro médio geométrico e ponderado), químicas (fertilidade básica e matéria orgânica), microbiológicas (carbono da biomassa microbiana, atividade microbiana e qCO2). Os resultados indicam que as práticas culturais e o manejo do solo adotado no sistema de produção orgânico e convencional contribuíram para um aporte expressivo de matéria orgânica atribuído à constante deposição da biomassa da bananeira, sem diferença com a área de referência de mata nativa, havendo, dessa forma, manutenção da qualidade física e microbiológica do solo. Os indicadores químicos apresentaram condições químicas favoráveis ao desenvolvimento do plantel nos sistemas orgânicos, e em especial nos sistemas convencionais, onde, além do material orgânico depositado, houve adição de insumos químicos. Ressalta-se as limitações da seleção dos indicadores químicos, os quais não avaliaram os efeitos dos insumos químicos utilizados nos sistemas convencionais, sendo este, o principal fator que diferencia o manejo realizado nos sistemas orgânicos e convencionais. Soil Quality under Banana Cultivation in Organic and Conventional Production Systems in Gonçalves (MG) ABSTRACTThe aim of this work was to evaluate the soil quality depending on different banana cultivation conventional and organic systems, through integrated analysis of physical, chemical and microbiological attributes, using an area of a native forest as reference. The deformed and not deformed samples were collected at a depth of 0 to 20 cm in the city of Gonçalves (Minas Gerais’ state), then undergo to physic analysis (texture, soil density, particle density, total porosity, weighted geometric mean diameter); chemical (soil fertility and organic matter); and microbiological (microbial biomass carbon, microbial activity and qCO2). The results indicated that the cultural practices and the soil management adopted in the organic and conventional productions system contributed to an expressive input of organic matter, improving soil quality in terms of physical, chemical and microbiological aspects. Thus, due to the similarity of soil quality, it is recommended that the practices of adding agricultural inputs to conventional production systems be reviewed.Keywords: use of the soil, banana cultivation, indicators of the soil quality.
