Effects of Fire on Soil and Water

Leaf and soil nitrogen and phosphorus availability in a neotropical rain forest of nutrient-rich soil.

The nitrogen and phosphorus supply in a lowland rain forest with a nutrient-rich soil was investigated by means of the leaf N/P quotient. It was hypothesised a high N and P supply to the forest ecosystem with a N and P rich soil. Total N and extractable P were determined in the surface (10 cm) soil of three plots of the forest. Total N was analysed by the Kjeldahl method, and P was extracted wi...

Effects of Arbuscular Mycorrhizal Fungi on Growth and Nutrient Uptake of Apple Rootstocks in Calcareous Soil

The effects of three Arbuscular Mycorrhizal Fungi (AMF) species (Glomus versiforme, Claroideoglomus etunicatum and Rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (M.9, M.7 and MM.106). The soil medium contained a high level of calcium carbonate (38.65%). The results showed that AMF inoculation could increase almost all growth parame...

Study on the Effects of Irrigation with Reclaimed Water on the Content and Distribution of Heavy Metals in Soil.

Reclaimed water is an important resource for irrigation, and exploration in making full use of it is an important way to alleviate water shortage. This paper analyzes the effects of irrigation with reclaimed water through field trials on the content and distribution of heavy metals in both tomatoes and the soil. By exploring the effects of reclaimed water after secondary treatment on the conten...
