Technology and Agribusiness – The Ethical Search for Increase Food Production

The problem of the present research lies in presenting techniques that may represent a common denominator between producing more and with quality, using less soil, concomitantly meeting the needs indicated in the 2030 agenda of the United Nations Organizations. With the advancement of research in the agribusiness sector, as well as the introduction of technology in agriculture, there is a potential means to find a balance between producing and protecting the natural environment. In this way, the present study is justified because the balance between producing and repairing the environment is the key to maintaining the planet for the next generations, in this sense, academic production is necessary to d...

Use of organic compost produced from slaughterhouse waste as fertilizer in soybean and corn crops

The effect of an organic fertilizer produced from slaughterhouse waste on the fertility of sandy and clayey soils as well as soybean yield (Glycine max L.) and corn (Zea mays L.) crops was evaluated. Field experiments were set up and five rates up to 16 t ha −1 of organic fertilizer (293 kg ha −1 N, 334 kg ha −1 P and 27 kg ha −1 K) were applied annually, before sowing in spring/summer, as well as a mineral fertilization of 300 kg ha −1 in the formulation 2-20-20 for soybean and 300 kg ha −1 of 12-15-15 for corn. The organic fertilizer changed soil fertility in the field experiments by increasing pH, Ca, Mg, K, P-Mehlich and P-resin. Such effects were more evident in the sandy than in the clayey soil, and the most superficial layer was affected more. The organic fertilizer rate needed to achieve maximum yield decreased for corn in both soils and for soybean in the sandy soil, although the amounts required may still be regarded as high.

In this way, the present study is justified because the balance between producing and repairing the environment is the key to maintaining the planet for the next generations, in this sense, academic production is necessary to discuss techniques that bring producers, researcher and society in general. To this end, the methodology used was qualitative bibliographic research, in which books, scientific articles, as well as content available on virtual channels of various bodies that deal with the theme were used. In the end, it was possible to verify that the indiscriminate use of soil and agricultural inputs imply the depletion of natural resources, however, the implementation of technology in food production represents the way to sustainable production, preserving and repairing the environment.

Quality of poultry litter submitted to different treatments in five consecutive flocks

It was used 640 birds per flock as a complete randomized design with eight treatments and four replicates. The treatments were the following: 1 non-treated litter; 2 litter submitted to in-house composting; 3 litter treated with aluminum sulfate; 4 litter submitted to gypsum; 5 litter treated with quicklime; 6 litter treated with dolomitic limestone; 7 litter treated with zeolite and 8 litter treated with charcoal. Chopped elephant-grass hay was used as poultry litter in all flocks. Fermentation in the shed increased moisture content of the litters in the second and first flocks on 21 and 42 days of breeding, respectively. There was no difference on density among treatments. Aluminum sulfate reduced pH of the litters in all flocks at 21 days of breding. On 42 days of breeding, pH of the litters was reduced in the l...

The experiment was done in field, in lineation of blocks randomly, with six treatments and four repetitions. The treatments consisted of poultry litter individually treated, with the following conditioners: limestone, zeolite, culm, Al 2(SO 4)3 and fermentation under canvas, under the dose of 10 t ha -1 , and witness (400 kg ha -1 of mineral formulated 02-20-18). After the harvest, threshing and weighing of grains were done, one obtaining grain productivity and dry mass of one hundred grains. One reported that only corn grain productivity has been significantly influenced by treatments.

Ammonia volatilization from surface application of organic residues and urea on Marandu palisadegrass

An experiment was conducted in a randomized block design, in plots repeated over time, with four treatments and four replications. The fertilizers tested were: mineral fertilizer (70 kg ha-1 N, 100 kg ha-1 P 2 O 5 and 30 kg ha-1 of K 2 O, as urea, triple superphosphate and potassium chloride, respectively), pig slurry (200 m 3 ha-1 applied in November 2008 and 200 m 3 ha-1 applied in April 2009) and poultry litter (10 t ha-1 applied in November 2008 and 10 t ha-1 applied in April 2009). Five evaluations were performed with 24-hour intervals. Foams were used with glycerin and sulfuric acid, internally fixed in PET bottles for collecting ammonia. After collected, the samples were sent to the laboratory to determine volatilized ammonia levels by the semi-micro Kjedahl distillation method. Fertilization with chicken litter had lower ammonia volatilization in relation to urea and pig slurry. Most of the ammonia volatilization from pig slurry occurred within 48 hours after application, totaling losses of 630 g kg-1 of a total of 8.25 kg ha-1 of volatilized ammonia. The biggest loss by ammonia volatilization was from fertilization with urea, totaling approximately 80 g kg-1 of N applied.
