Information on soil fertility is essential to determine the need for correcting measures. However, the use of appropriate techniques to provide information on the specific potential of each soil in many agricultural areas is scarce. Soil fertility in an area with family farming was evaluated based on spatialization of soil chemical attributes to indicate their usage limitations. The study area was on the water basin of the Natuba River, in the Mata Centro Zone, Pernambuco state, Brazil. Samples were taken from soils under the most representative agricultural uses and under native vegetation following a slope gradient (top, middle and bottom). Samples were analyzed for their base saturation, cation exchange capacity, aluminum saturation and phosphorus concentration. These parameters were used to indicate their degree of limitation to agricultural use in order to create a georeferenced database and were mapped using a Geographic Information System (GIS). The cultivated Rhodic Acrisol and Eutric Gleisol had the highest fertility, while the Xanthic Acrisol, Chromic Acrisol and Xanthic Ferralsol had the highest usage limitations. Areas used to grow vegetables had higher nutrient availability than those cropped to sugarcane. Spatialization in the GIS system contributed to the overall fertility analysis, allowing a clear visualization of areas that need soil improvement. |

Abstract - An experiment of a factorial structure of threee genetic potentials fõr mature size (WMA) (30, 40 and 50kg of body weight) by three genetic potentials for rnilk production (MIILK) (1.125, 1.500, and 1.875kg of milk x ewe x day 1 at the peak day of lactation) by three genetic potentials for ovulation rate (Ova) (1.65, 2.20 and 2.75 ova x o.vulation') in a total of 27 genotypic combinations were simulated. Simulation results showed efficiency of sheep meat production for Northeast Brazil (total weight sold x ton of dry matter consumed hy the flocC 1 x year) increased with increases in genetic potential for ovulation rate and with increases in genetic potential for milk production, but it decreased with increases in genetic potential for inature size. The most efficient genotype was the one wJ.th medium WMA, medium MILK or high OVR, followed closely by the genotypes with medium WMA, low MILK and high OVR, and by low WMA, ruedium MILK and high OVR. High WMA genotyps were not present in the eleven genotype combinations ranked above the base genotype. [Genótipos potenciais para ovinos Morada Nova]. REsumo - Foi conduzido um experimento simulado com desenho em estrutura fatorial com tres potenciais geneticos para tamanho a maturidade (WMA) (30, 40 e 50Kg de peso vivo), tres potenciais geneticos para producao de leite (MILK) (1,125. 1,500 e 1,875Kg de leite X dia -1 X ovelha no pique de lactacao -1) e tres potenciais geneticos para taxa de ovulacao (OVR) (1,65, 2,20 e 2,75 ovulos X ovulacao -1) num total de 27 combinacoes genotipicas. Os resultados da simulacao mostraram que a eficiencia de producao de carne ovina no Nordeste do Brasil (peso total comercializado X materia seca total consumida pelo rebanho -1 X ano -1) aumenta com aumentos no potencial genetico para producao de leite, mas diminui com aumentos no potencial genetico para peso a maturidade. O genotipo mais eficiente foi aquele com WMA medio, MILK medio e alta taxa de ovulacao seguido de perto por genotipos com medio WMA, baixo MILK e alto OVR e por baixo WMA, medio MILK e alto OVR. Genotipos com alto WMA nao apareceram na lista das onze combinacoes genotipicas superiores as genotipo base.
