Conservation agriculture is often presented as being ‘climate smart’ due to anticipated increases in soil moisture. The extent of enhanced water availability in farmers’ fields is, however, poorly documented. This paper presents five data sets describing soil moisture in fields of small-scale conservation and conventional farmers in the Agro-ecological Zone IIa, Zambia. The data include (1) soi...

Brazil’s emergence as a primary global agricultural producer is often credited to production expansion into soils of the Brazilian savannah or Cerrado. These soils are, however, deficient in important nutrients and prone to degradation, requiring input-intensive processes that suggest a low level of productive efficiency. Employing a sequence of agricultural censuses and a biome approach for ch...

The importance of managing land to optimize carbon sequestration for climate change mitigation is widely recognized, with grasslands being identified as having the potential to sequester additional carbon. However, most soil carbon inventories only consider surface soils, and most large-scale surveys group ecosystems into broad habitats without considering management intensity. Consequently, li...

State-and-transition models are increasingly being used to guide rangeland management. These models provide a relatively simple, management-oriented way to classify land condition (state) and to describe the factors that might cause a shift to another state (a transition). There are many formulations of state-and-transition models in the literature. The version we endorse does not adhere to any...

Soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. Organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure.So, this research has been done for achieving this purpose. This area is arounding sa...

Objective: The main purpose of this research is review of principles, concepts, problems and solutions of soil ethic.

Matthew 13, the third of Jesus' five major discourses in Matthew, includes the Lord's address to the crowds (vv. 1-35) and His address to the disciples (vv. 36-52). This chapter contains His presentation of the mysteries of the kingdom of heaven which He revealed in response to the Jewish leaders' rejection of Him (12:1-45). This section focuses on the new and unexpected phase of the kingdom of...
