Abstract: In order to develop a method for extensive pomiculture on marginal soils in semiarid Brazil, a field experiment was conducted to study the impacts of the soil conditioners biochar, clay substrate and goat manure on soil physical parameters of a sandy soil and on seedling performance of Spondias tuberosa Arruda. Manure significantly increased total porosity, soil water content and reduced bulk density of the sandy soil. Water content at field capacity (θfc) and at permanent wilting point (θpwp) were increased due to manure application. Neither biochar nor clay substrate had a significant impact on the soil physical parameters. Biochar combined with clay substrate led to lower soil water content and significantly reduced the period of retaining atmospheric water. Due to a strong correlation (R2 = 0.75) between θfc and θpwp, the available water capacity within all treatments remained unchanged. Amelioration and initial nutrient supplies had no effect on seedling survival and stem growth of S. tuberos...

Effects of biochar application in forest ecosystems on soil properties and greenhouse gas emissions: a review
Yongfu Li,Shuaidong Hu,Junhui Chen,Karin Müller,Yongchun Li,Weijun Fu,Ziwen Lin,Hailong Wang,Hailong Wang +8 more
TL;DR: In this paper, a review of the available literature on the effects of biochar on soil properties and GHG emissions in forest soils is presented, where the authors focus on the negative impacts of intensive forest management and global climate change on the quality of forest soils via soil acidification, reduction of soil organic carbon content, deterioration of soil biological properties, and reduction of the soil biodiversity.

Estimating saturated soil hydraulic conductivity by the near steady-state phase of a Beerkan infiltration test
TL;DR: In this paper, a simplified version of the simplified method based on a Beerkan infiltration run was developed to estimate saturated soil hydraulic conductivity, Ks, by only using the near steady-state phase of a beerkan infiltrate run and an estimate of the α* parameter.

Effects of biochar on the accumulation of necromass-derived carbon, the physical protection and microbial mineralization of soil organic carbon
TL;DR: In this article , a review of the effects of biochar on the buildup, protection, stabilization, and mineralization of soil organic carbon (SOC) is presented, which highlights the pivotal role of microbial necromass in the formation of soil stable carbon pool.

Unraveling the water and land nexus through inter- and transdisciplinary research: sustainable land management in a semi-arid watershed in Brazil’s Northeast
TL;DR: In this paper, a synthesis assessed sustainable land management options by investigating the aquatic and terrestrial land use systems alongside their underlying ecosystem functions and services, and concluded that the primarily hydroelectricity-focused water management practice cannot be maintained at the same level in the long run, as it has become ever more adverse towards competing water usages.

TL;DR: The World Reference Base for Soil Resources (WRB) is an international soil classification system for naming soils and creating legends for soil maps as discussed by the authors, which has two hierarchical levels: the first level presents 32 Reference Soil Groups (RSGs), which are identified using a key.
The reduction of water repellency by added clay is influenced by clay and soil properties
TL;DR: In this article, the response of water repellency to added clays dominated by kaolin or smectite was investigated for 23 highly water- repellent sandy soils from the West Midland Sandplains, Western Australia.
