“…Studies into organomineral fertilizers in solid form have shown their greater benefits to the chemical properties of the soil, and even increased crop yield, compared to mineral-derived fertilizers (Babalola et al, 2007;Correa et al, 2016). For organomineral fertilizers in fluid form, however, research has been scarce.…”

The objective of this work was to evaluate the effects of organomineral and mineral fertilizers, in their solid and fluid forms, on soils with variable charges with high fertility built up from nitrogen, phosphorus, and potassium contents in the soil and plant, as well as on corn (Zea mays) and black oat (Avena strigosa) yield. The treatments consisted of one control and four fertilizers - two organomineral and two mineral - in solid (SO, solid organomineral; and SM, solid mineral) and fluid (FO, fluid organomineral; and FM, fluid mineral) forms applied in Rhodic Kandiudox and Distrochrept soils with no-tillage. The use of organomineral or mineral fertilizers in fluid and solid forms increases total N content in the soil, maintains exchangeable K content in both soils, and may enhance available P content to the depth of 0.6 m in Distrochrept. These factors allowed significantly increasing corn yield, regardless of the fertilizer, and establishing greater residual effect for fluid organomineral fertilizer in the winter black oat yield, even in soils with high fertility.

“…Release of N from the organomineral fertilizer is more gradual than in the other sources. Therefore, gradual release of N from this fertilizer may have provided lower synthesis of amino acids and sugars in the apoplast, and this may explain the lower incidence of CLM in our study (CARDOSO;LUZ;LANA, 2015;CORRÊA et al, 2016).…”

The coffee leaf-miner (CLM) Leucoptera coffeella (Lepidoptera: Lyonetiidae) is one of the main pests of coffee plants in Brazil. Its occurrence in the crop is directly related to the physiological state and growth characteristics of coffee plants, in turn related to plant nutrition. The present work, therefore, aimed to evaluate the effect of nitrogen sources on the occurrence of CLM in coffee seedlings. The fertilizers used were ammonium sulfate, urea, and organomineral. The number of leaves mined by CLM and the relative contents of chlorophyll and crude protein in the leaves were recorded. Ammonium sulfate and urea favored higher occurrence of leaves mined and organomineral fertilizer provided the lowest incidence of leaves mined by CLM. The three sources of nitrogen increased the chlorophyll content, but only ammonium sulfate caused an increased percentage of crude protein in the leaves of coffee seedlings. For the improvement of management strategies for L. coffeella it is fundamental to understand favorable conditions, nutritional management it is one of the pest control mechanisms, thus making it possible to control the insect and prevent the population of CLM from reaching an economic damage threshold.

“…No tratamento convencional, a rápida solubilização das fontes minerais de N pode ter acarretado menores valores de NH 4 + nesse sistema. Fertilizantes minerais fornecem N mais rapidamente ao solo devido ao aumento da solubilidade físicoquímica dos seus grânulos (CORREA et al, 2016).…”

The growing demand for specialty coffees, prioritizing product quality and environmental sustainability has promoted organic coffee production and increased interest in the assessment of soil quality bioindicators measuring the effects of management systems. The aim of this work is to evaluate parameters of soil bioindication quality in coffee plants due to organic and conventional fertilization, using native forest soil as a reference. The experiment happened in Monte Carmelo-MG, with the cultivar Catucaí Amarelo 20/15 cv 479 in a randomized block designed with five blocks. The treatments consisted in the application of organic compost and liquid organic fertilizer via "drench and the conventional treatment of the farm (spectator). Three subsamples per experimental plot were collected in the projection from the top of the coffee and in an area of native forest close to the experiment, resulting in a sample composed of each treatment plot. The parameters pH, electrical conductivity, basal soil respiration, labile carbon, assimilable phosphorus and ammoniacal nitrogen were evaluated. The soil under organic fertilization provided levels of ammoniacal nitrogen and assimilable phosphorus higher than the conventional system, however ammoniacal nitrogen was lower than the soil under native vegetation, for labile carbon were similar in both soils. Regarding electrical conductivity, they must constantly monitor the soil under cultivation to avoid elevation to toxic levels for the coffee plant. In general, the soil under organic fertilization does not contribute to the improvement of biological activity, but maintained or increased values of phosphorus and Clábil.
