Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

Progressive N limitation of plant response to elevated CO2: a microbiological perspective
Abstract A major uncertainty in predicting long-term ecosystem C balance is whether stimulation of net primary production will be sustained in future atmospheric CO2 scenarios. Immobilization of nutrients (N in particular) in plant biomass and soil organic matter (SOM) provides negative feedbacks to plant growth and may lead to progressive N limitation (PNL) of plant response to CO2 ...

Effect of biochar on maize yield and yield components in rainfed conditions
Int. J. Agron. Agri. Res. 12(3), 46-51, March 2018. To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. The treatments were control, wheat straw biochar at 5t ha-1, and 10t ha-1, sugarcane ...

Top 10 Advantages of Organic Fertilizers for Agriculture and Farming
Fertilizers supplement the nutrients already present in the soil. The fertilizing products can be vaguely classified as Organic or Natural Fertilizers and Synthetic or Man-Made Fertilizers. While synthetic or chemical fertilizers are concentrated, strong and quick enough to dissolve in the soil immediately, Organic Fertilizers for plants release nutrients slowly with time and often contain many ...

Productivity of ephemeral headwater riparian forests impacted by sedimentation in the southeastern United States coastal plain
Received for publication April 30, 2008. Riparian forests serve an essential function in improving water quality through the filtering of sediments and nutrients from surface runoff. However, little is known about the impact of sediment deposition on productivity of riparian forests. Sediment inputs may act as a subsidy to forest productivity by providing additional nutrients for plant uptake or ...

Influence of microbial activity on plant–microbial competition for organic and inorganic nitrogen
Abstract To investigate how the level of microbial activity in grassland soils affects plant–microbial competition for different nitrogen (N) forms, we established microcosms consisting of a natural soil community and a seedling of one of two co-existing grass species, Anthoxanthum odoratum or Festuca rubra. We then stimulated the soil microbial community with glucose in half of the microcosms ...

Influence of environment on plants
There is no denying the importance of light for the growth of plants; however, there are many other environmental factors—such as temperature, moisture and nutrient availability, and soil type–that also influence plant growth. These factors do not act in isolation and are, many times, correlated. So, it is interesting to see how light works in combination with other resources to ...

How three U.S. mini-farms are sowing the seeds of global food security
Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...
