The significance of atmospheric nutrient inputs and canopy interception of precipitation during ecosystem development in piñon-juniper woodlands of the southwestern USA [PDF]

open access: yes, 2013
In arid ecosystems, widely spaced vegetation and prolonged dry periods may enhance canopy capture of nutrients from dry deposition. Additionally, differences in precipitation type, plant canopy architecture, and soil nutrient limitation could affect ...

Microbial pathogenesis and the evasion strategies from the legume plant protective immunity

open access: yesLegume Science, 2023
Plants are stringent sources for the global food supply, and among them, legumes are considered to be the special ones since they have the specific capability to develop a symbiotic relationship with certain soil microorganisms (i.e., the rhizobial ...

Sugarcane Bagasse Is an Effective Soilless Substrate Amendment in Quick-turn Osteospermum Production

open access: yesHortScience, 2023
Many greenhouse growers rely on peat-based soilless substrates to produce salable crops in a relatively short period of time. Peat-based substrate suppliers often incorporate additional organic materials such as wood fiber to extend peat supplies.

A targeted management of the nutrient solution in a soilless tomato crop according to plant needs [PDF]

open access: yes, 2016
The adoption of closed soilless systems is useful in minimizing the environmental impact of the greenhouse crops. Instead, a significant problem in closed soilless systems is represented by the accumulation of ions in the recycled nutrient solution (NS),

An optimized method for extraction and purification of inorganic phosphate from plant material for oxygen isotope ratio analysis

open access: yesMethodsX
Compound-specific stable isotope ratio analysis of oxygen isotopes in inorganic phosphate can be used to study biological phosphorus cycling and the transformation processes controlling the fate of phosphorus. However, methods for extraction of inorganic

Nutrient Sensing in Plants [PDF]

open access: yesMolecular Plant, 2012
Higher plants require a number of essential nutrient elements for completing their life cycles. Mineral nutrients are mainly acquired by roots from the rhizosphere and are subsequently distributed to shoots. To cope with nutrient limitations, plants have evolved a set of elaborate responses consisting of sensing mechanisms and signaling processes to ...

Against the grain [PDF]

open access: yes, 2011
An Organic Research Centre project is examining how diversity-based tools can assist in the on-farm improvement of organic wheat. Successful organic crop production requires varieties that are resistant to diseases, competitive against weeds, and ...
