| The present experiment was carried out to assess influence and inter-relationships of soil properties in grasslands of three wildlife protected national parks in Central India. Aboveground biomass samples of grass and soil samples were collected during different seasons based on specified measurement protocol by the state forest department. Aboveground biomass of grass demonstrated a characteristic growth pattern throughout the year, increased and achieved maximum biomass during at the end of rainy season (September), while started decreasing and attained minimum biomass during pre-summer (March) season. Mean aboveground biomass in the study regions was varied from 2.03 (Bandhavgadh National Park) to 5.44 Mg ha-1 (Kanha National Park) with an average... |

| Currently, agricultural productivity and sustainable development are the desired bases for the creation of production systems. Farming for greater production and the efficient use of soil resources are at the core of modern systems. However, the way in which agricultural management and practices can change soil quality has become increasingly important. The aim of this study was to detect changes in soil biological properties caused by implementation of the integrated crop-livestock-forest system (iCLF) and to identify the properties suitable for detecting changes in soil biological quality. Soil samples were collected from the 0.00-0.10 m layer in Nova Canaã do Norte, MT, Brazil, and Cachoeira Dourada, GO, Brazil, in areas of the iCLF with 1 (iCLF1) or 3... |

| Nas áreas de capoeiras, na fase sucessional de revegetação, onde anteriormente foram cultivados o milho, feijão e mandioca, durante dois a três anos, uma espécie pioneira, conhecida popularmente como “Pimenta Longa”, tem se destacado como uma alternativa de renda para os pequenos agricultores da Amazônia Ocidental. Esta espécie pioneira, despertou interesse de grandes empresas, em virtude das possibilidades de atender uma demanda crescente do mercado internacional de "safrol", subproduto extraído do óleo essencial de algumas plantas, o qual é utilizado principalmente pela indústria de cosméticos e inseticidas biodegradáveis. Considerando a ocorrência natural da Pimenta Longa no Estado e com o objetivo de avaliar a influência das características físicas e... |

| Soil chronofunctions are an alternative for the quantification of soil-forming processes and underlie the modeling of soil genesis. To establish soil chronofunctions of a Heilu soil profile on Loess in Luochuan, selected soil properties and the 14C ages in the Holocene were studied. Linear, logarithmic, and third-order polynomial functions were selected to fit the relationships between soil properties and ages. The results indicated that third-order polynomial function fit best for the relationships between clay (< 0.002 mm), silt (0.002-0.02 mm), sand (0.02-2 mm) and soil ages, and a trend of an Ah horizon ocurrence in the profile. The logarithmic function indicated mainly variations of soil organic carbon and pH with time (soil age). The variation in... |

| ABSTRACT An incubation experiment was conducted to examine the effects of nitrogen (N) applications in different forms (NH4NO3, NH4Cl, and KNO3) on microbial respiration considering 3 different alpine meadow soils (C poor soil, pH = 8.1, 1.6% C; C moderate soil, pH = 6.0, 5.0% C; C rich soil, pH = 7.1, 7.4% C) in the Tibetan Plateau. The addition of NH4NO3 and NH4Cl increased the microbial respiration in C poor soil, but KNO3 had no effect. The inorganic N forms had no effects on C rich soil, but decreased microbial respiration in C moderate soil. Soil microbial respiration levels across the different types were ordered as follows: C poor soil < C rich soil < C moderate soil, regardless of N addition. These results suggest that the effect of N on... |

| O objetivo deste trabalho foi avaliar as variações nos atributos do solo em função de diferentes estados de conservação de pastagens nativas localizadas nas áreas úmidas no Pantanal da Nhecolândia, Mato Grosso do Sul. As pastagens nativas avaliadas encontram-se em bordas de baias e o estado de conservação das pastagens (ECP) foi determinado a partir do percentual de cobertura de espécies forrageiras, classificados em três diferentes estados de conservação: ótimo (> 80% de cobertura de forrageiras), regular (65 a 80% de cobertura de forrageiras) e marginal (15 a 65% de cobertura de forrageiras). Amostras de solo foram coletadas em cada ECP, nas profundidades de 0-10, 10-20 e 20-40 cm, com três repetições, e submetidas a análise química. A maior... |

| This paper presents the study of the relationship between electrical properties and physical characteristics of the soil. Measures of apparent electrical resistivity of the soil were made for different types of soil, varying moisture content gradually while maintaining a constant compaction, and then varying the compaction and relating it to a constant humidity. Development of a correlation surface is proposed in order to identify granulometry of the soil from moisture and compaction measurements. For the study of spatial variability, two areas were chosen to allow the change of moisture content and compaction in order to verify the measurement capacity of apparent electrical resistivity of the soil as methodology to identify change in soil dynamics.... |

| Aero geophysical data is becoming an important source of environmental covariate in digital mapping. Airborne gamma-ray spectrometry is more common in digital soil mapping, because of the penetration potential of approximately 30-40 cm. However, the airborne magnetic method can be tested to add and improve the prediction of soil properties. Therefore, the objective of this work was to implement a preliminary study to model the spatial distribution of soil properties using pedological legacy data, aero geophysical data, and terrain covariates to discuss their importance to the digital soil mapping in Bom Jardim county, Rio de Janeiro, Brazil. |

| Soils in urban areas often present characteristics that might submit these environments to erosion processes. Applying municipal solid wastes (MSW) composts to soils have been suggested as a means to improve physical and chemical properties. A field experiment with a completely randomized design was conducted in a Typic Argiudoll from a degraded area in Buenos Aires City. The objective was to evaluate the effect of MSW compost application on soil properties, residue decomposition and Poa (Poa pratensis L.) reestablishment. At the beginning of the trial, compost was prepared and applied in a bare soil on 0.25 m² square plots afterwards litterbags were incorporated and Poa was sown. Compost amounts were: 0 (control); 2 (low); 4 (medium) and 7 kg m-2 (high)... |

| ABSTRACT: Phytotoxic effects of allelopathic crop residues are important to trickle for their use as a source of organic amendments to improve soil fertility. In present study, through pots and two year field studies, we examined the integrated effect of allelopathic residues and NPK fertilizer treatments including T0 (control), T1 (200-150-100 kg NPK ha 1), T2 (100-75-50 kg NPK ha-1 + mung bean straw 4 t ha-1), T3 (100-75-50 kg NPK ha-1 + rice straw 4 t ha-1), T4 (mung bean straw 8 t ha-1) and T5 (rice straw 8 t ha-1) under different water regimes on soil fertility and wheat crop. Solo application of mung bean residue and rice straw caused significant inhibition of various germination and growth traits of wheat while minimal inhibition occurred when... |
