Seed and seedling ecology of four Agulhas Proteaceae
… and Leucadendron meridianum occur on shallow, alkaline soils overlying limestone, and P.susannae and L.coniferum on adjacent, deep, weakly acidic sands, in fire-prone fynbos. Seed reciprocal transplants were used to test whether regeneration niche requirements were determinants of adult …

The role of organic matter and other soil properties in Zn2+ activity and AB-DTPA-extractable Zn in soils
… well as a potential heavy metal contaminant in soils. In soil solution, the free Zn activity determines the availability of Zn as a micronutrient and its characteristics as a heavy metal contaminant. A better understanding of the mechanism that controls free Zn activity could improve soil …

Chemical and Physical Characteristics of Saline Soils in Grand Forks county North Dakota
<p>Saline soils reduce the productivity of over 80,000 hectares, or 23% of the land area, in Grand Forks County, an agricultural county in eastern North Dakota. A geochemical analysis was completed on soils from two salt-affected areas to determine if the salinity is depression-focused in saline …

Pressurized Hot Water and DTPA-Sorbitol, Viable Alternatives for Soil Boron Extraction
… were conducted on one limed acid and two alkaline soils naturally low in B to test alfalfa response to B fertilizer. Values from the three soil extraction methods were correlated to yield, B tissue concentration and total B removal of alfalfa. In greenhouse studies with varying levels of …

The Role Of Mimosine, A Non-protein Amino Acid In Leucaena Leucocephala Subsp. Glabrata (giant Leucaena)
… low soil fertility, salinity, acidic and alkaline soils, and disease and pest infestation. The entire plant of giant leucaena contains a non-protein amino acid, called mimosine, which is also toxic to animals. High amounts of mimosine is found in the foliage, especially in the young …

The effects of biochar on soil mineral availability
… with a non-biochar control in 2 different soils (Luvisol & Calcisol) present in Malta, in which Lactuca sativa was cultivated in pots in a greenhouse experimental setup for 7 weeks. The key findings of the study demonstrated that Lactuca sativa crops grown in biochar amended soils contained …

Environmental Controls Over the Distribution and Function of Antarctic Soil Microbial Communities
… within certain habitats (i.e. Acidobacteria in alkaline soils, Nitrospira in mesic soils) suggesting the presence of niche specialists and spatial heterogeneity of taxa-specific functions (i.e. nitrite oxidation). Additionally, environmental parameters had different explanatory power towards …
