“…The highest values obtained for bovine manure treated plants (Figure 1) are responses to higher nutrient concentrations compared with biofertilizers (Table 2) and to the action of manure as a soil physical conditioner. Manure provides increased porous space to the radicular system (DUNJANA et al, 2012) and improved soil fertility (BENBOUALI et al, 2013;SILVA et al, 2014), resulting in greater vegetative growth compared with soil treated with biofertilizers diluted in water. The superiority of the chemically enriched biofertilizer over the common fertiliser is due to its additional components such as plaster (a source of calcium and sulphur) (LEITE et al, 2010), cow's milk (rich in proteins, vitamins, calcium, phosphorus, potassium, magnesium and zinc) (NASCIMENTO et al, 2010) and molasses (a source of sugars, phosphorus, potassium, calcium, magnesium, sulphur and iron) (COPERSUCAR, 1988).…”

“…Despite these advantages, studies on the prolonged effect of these organic inputs in reducing soil sodicity and plant productive performance are still scarce. According to Silva et al (2014), bovine manure slowly releases nutrients to the soil, while Marrocos et al (2012) state that liquid biofertilisers act quickly, with the majority of their nutrients available only during the first fifteen days post application.…”

-Soil salinity and sodicity are global problems since both promote the physical, chemical and biological degradation of soil, jeopardising the productive capacity of agricultural fields. Inorganic correctives or organic inputs are applied as an attempt to reduce the problem, alongside the use of salt-tolerant plants. This study aimed at evaluating the effects of organic inputs on the growth of neem (Azadirachta indica) strains in saline-sodic soil after cutting. Treatments were arranged in a randomised block design, with four replicates in a 3 × 5 factorial. Organic inputs -bovine manure, common bovine biofertilizer (equal parts of water and fresh bovine manure) and chemically enriched biofertilizer (common biofertilizer components combined with plaster, sugarcane molasses and cow's milk) -were applied only once, after soil washing, two days prior to seeding, at the levels of 0, 3, 6, 9 and 12% of the substrate volume. Except effects on the stem diameter, the most efficient input was bovine manure, with strong effects on the height increase and biomass yield of neem plants after cutting, especially in treatments at a level greater than 6%. The organic inputs, despite increasing the soil salinity and sodicity in the interval between washing and cutting, stimulated biometric growth and biomass formation in saline-sodic soil.Keywords: Azadirachta indica.

REBROTA E CRESCIMENTO DO NIM APÓS O CORTE EM SOLO SALINO -SÓDICO TRATADO COM INSUMOS ORGÂNICOSRESUMO -A salinidade e a sodicidade dos solos são problemas mundiais porque promovem a degradação das propriedades físicas, químicas e biológicas dos solos e comprometem a capacidade produtiva das áreas agrícolas. Uma das tentativas de redução do problema é a aplicação de corretivos inorgânicos ou insumos orgânicos associados com plantas tolerantes aos sais. Pelo exposto, o trabalho objetiva avaliar o efeito de insumos orgânicos na rebrota de cepas de nim (Azadirachta indica) após o corte no crescimento das plantas em solo salino -sódico. Os tratamentos foram arranjados em blocos ao acaso, com quatro repetições em esquema fatorial 3 × 5, referentes aos insumos orgânicos -esterco bovino, biofertilizante bovino comum (partes iguais de água e esterco fresco de bovino) e biofertilizante enriquecido quimicamente (componentes do biofertilizante comum associados a gesso, melaço de cana -de -açúcar e leite de vaca), aplicados uma única vez, após a lavagem do solo, dois dias antes da semeadura das sementes, aos níveis de 0, 3, 6, 9 e 12 % do volume do substrato. Exceto no diâmetro caulinar, o esterco bovino foi mais eficiente que os biofertilizantes no crescimento em altura e rendimento em biomassa das plantas de nim após o corte, principalmente nos tratamentos em níveis acima de 6 %. Os insumos orgânicos apesar de elevarem a salinidade e a sodicidade do solo no intervalo do final da lavagem até o corte das plantas, estimularam o crescimento biométrico e a formação de biomassa do nim em solo salino sódico.Palavras-chave: Azadirachta indica.

“…Study of Behera et al (2018) and Coletto et al (2015) also used PCs to show nutrient dynamics over time in soil. Applications of animal manure take 90 days to increase the content of nutrients in the soil, with the first 30 days showing a greater release rate and a subsequent decline (Silva et al 2014). The remaining nutrients in animal manure take more time to be released in the soil as long as 2.5 years (Hoffmann et al 2001), but this will depend greatly on the quality of animal manure (Azeez and Averbeke 2010;Silva et al 2014).…”

“…The results of CoM characterized it as a manure of slow decomposition with 28% of the material decomposed within 90 days. Slow decomposition of CoM in soil was presented by the study of Azeez and Averbeke (2010) and Silva et al (2014). The increase in organic matter temporally promotes an adsorption of P in soil (Muraishi et al 2011;Maciel et al 2015;Abreu et al 2016), with a lower nutrient loss by run off and leaching while maintaining an optimal condition of pH, soil moisture and soil biological activity (Moreti et al 2007).…”

Purpose Due to the pressures of conforming to environmental quality standards and the increased costs of mineral fertilizer importation, there is growing interest in the use of organic residues as fertilizers. To test the hypothesis that indicates the quantity of animal manure (AM) depends on the phosphorus (P) needs of the crops, an experiment was run using three organic animal manures (chicken-CM, turkey-TM, and cow manure-CoM), enriched with limestone, gypsum, and phosphorus. Methods A greenhouse experiment was run using AM incorporated in a clayey soil, at a rate that equates to the P needs of Brachiaria sp. Contents of phosphorus, potassium (K + ), calcium (Ca +2 ), magnesium (Mg +2 ), sodium (Na + ), organic matter (OM), and values of pH and cation exchange capacity (CEC) were monitored during 120 days. Plants were collected to determine the dry matter.

The effect of mineral salts on water ingestion and urine volume in cattle has been extensively studied. However, recently, this effect has been investigated as a potential mitigator of environmental aspects related to the nitrogen (N) cycle, such as nitrate (NO) lixiviation, ammonia (NH) volatilisation, and nitrous oxide (NO) emissions. The effect of mineral salts, particularly sodium chloride (NaCl), on urine-N concentration, urine volume, the proportion of N compounds in the urine, and faecal-N concentration has not yet been explored in field conditions with respect to environmental aspects of beef cattle production. The present study investigated the effect of dietary mineral salt rates on these parameters. A Latin square (5 × 5) experimental design was utilised with five concentrations of mineral salts in the diet: 0.0, 2.0, 4.0, 6.0, and 8.0 g based on dry matter (DM) ingestion (g/kg DM). The nitrogen concentration in the urine and urine volume increased linearly. The total N excreted (g/day) via urine did not vary with increasing mineral salt concentrations. When evaluated, the N compounds of urine (urea-N, allantoin-N, and hippuric acid-N) also reacted to the increased mineral salt concentrations, while creatinine-N did not. Urea-N, allantoin-N, and hippuric acid-N linearly increased their proportions in total N-urine. The N concentration in faeces was not affected by mineral salt concentrations. The urine volume, concentration of N, and proportion of N compounds in the urine affected NO emissions and NH volatilisation. Therefore, mineral salt utilisation may be an option for mitigating N pollution from beef cattle, especially for grasslands in tropical countries.
