“…The application of lime or gypsum, alone or combined, increased the accumulation of Ca, Mg and S. Potassium (K) was more accumulated in treatments with isolated amendment, possibly because it was displaced in the soil in the LG treatment, due to the large amount of Ca 2+ (Soares et al, 2018). Even for the nutrients where accumulation in the shoot and root was not signi cant, the amendment altered their partition in the plants, resulting in more N and K transported to the shoot than retained in the root.…”

Introduction Maize (Zea mays L.) plays a fundamental role in Brazilian agriculture, and it is mostly cultivated in Brazilian Savannah areas, under high Al content and acidic pH. Aims The aim of this work was to evaluate the effects of soil amendments and A. nodosum extract on the initial development of the root system and nitrogen use efficiency of maize under aluminum toxicity. Methods The effects of lime and gypsum in combination with seed treatment + foliar application of Ascophyllum nodosum on shoot and root growth, plant nutrition and photosynthesis of 14-day-old maize seedlings were tested in two experiments. The experimental design was randomized 4x2 factorial, with the following treatments: lime (L), gypsum (G), lime + gypsum (LG) and control (C), cultivated with and without seed treatment and foliar application of the Ascophyllum nodosum. Results The treatments with A. nodosum extract led to an increase in the root area in the treatments with lime, and to a smaller transport of aluminum to the shoot of the plants. The lime and gypsum treatments were efficient in minimizing the deleterious effects of aluminum toxicity, even with their short-term application in sandy clay loam medium textured soil, providing better photochemical activity, better use efficiency of nutrients, better rooting and, consequently, higher dry weight of shoot and root. Conclusions The results show that the use of A. nodosum and soil amendments in acidic soils lead to promising physiological and morphological improvement, and by consequence, may influence in crop production.

“…The increase of the product demand in the market has also been motivating producers, who employ family labor force, to increment the cottage industry, which resulted in increased income for that segment (Pereira Filho et al, 2011). Maize grain is the predominant crop used in succession to soybean (Freddi et al, 2017;Soares et al, 2018) and with potential to succeed other crops, such as the industrial tomato. However, evaluation has not yet been performed as to the residual effect of fertilizers applied to tomato crop to supply the demands of the green maize grown in succession.…”

The study evaluated the agronomic performance of green maize grown on residual organomineral fertilization used in the industrial tomato crop. The randomized block design was used, with three replications and eight treatments as follows: control (without fertilizer application); mineral fertilizer; cattle manure; organomineral with cattle manure + MAP (monoammonium phosphate); chicken manure; organomineral with chicken manure + MAP; broiler litter; and organomineral with broiler litter + MAP. All of those treatments were applied to the tomato crop that preceded the green maize crop. After the tomato harvest, maize was sown in the same tomato growing row. Growth variables of green maize plants and ears were evaluated. The green maize grown in areas with residues of chicken and cattle manure, used as fertilizers in the tomato crop preceding the maize crop, resulted in a number of commercial ears similar to when mineral fertilizer was used. The same similar results were obtained for ear quality and yield. The use of organic fertilizers in the industrial tomato crop presented high viability, which made possible to replace the use of mineral fertilizers in the subsequent green maize crop.

Phosphorus (P) supply to crops is a major constraint on the quantity and quality of food production in tropical soils, which are often characterized by highly weathered soils having low phosphorus use efficiency. Increasing P fertilizer use efficiency is a good tool for increasing food production to feed an increasing world population. Enhanced efficiency P fertilizer is used to achieve this goal. The lack of information about soil P diffusive flux and corn and common bean yield response with increased efficiency P fertilizers justify studies to evaluate the performance of this type of fertilizer. The aims of this study were to evaluate P diffusive flux and corn and common bean crop response to P sources and rates. A laboratory trial was carried out to evaluate soil P diffusive flux in response to P sources (MAP and Policote coated MAP). Field trials were carried out to evaluate corn and common bean yields in response to P sources (MAP and Policote coated MAP) and rates. Policote, an additive based on water-soluble polymers, is an anionic copolymer with iron an aluminum affinity. Increasing contact time between P-fertilizers and soil reduced phosphorus diffusive flux. Policote coated P-fertilizer resulted in higher phosphorus diffusion than conventional phosphorus fertilizer. Phosphorus fertilization increased corn and common bean yields. Policote coated phosphorus fertilizer resulted in higher agronomic P efficiency use, corn, and common bean yields than conventional phosphorus fertilizer. Policote coated P fertilizer can be used as an enhanced efficiency fertilizer and is a more efficient way to deliver required phosphorous to plants. Reducing farm investment, increasing agricultural profits, preserve phosphatic rocks reserves, and avoid the overuse of phosphate fertilizer could be realized through the rational use of enhanced efficiency fertilizers and fertilizer rate use reduction.
