Predicting rice yield response to midseason nitrogen with plant area measurements
A simple method is needed to aid farmers with midseason nitrogen (MSN) decisions in dry-seeded, delayed flood rice (Oryza sativa L.). This study was conducted to develop thresholds using visual and digital image measurements for predicting rice yield response to MSN. ‘Francis’ and ‘Cheniere’ rice were drill seeded on 19-cm row spacing from 2004 to 2006 on silt loam and clay soils at Glennonville ...

Compost stability: a comparative evaluation of respirometric techniques
The new Paradigm in waste management promotes attitudes and processes that conserve resources and reduce pollution. Under this philosophy, organic waste is increasingly recognised as a recyclable material, a useful resource, making composting one of the key elements of modern waste management. As the composting industry is expanding rapidly there is a growing need for a simple, fast, relatively ...

Nitrogen Fixers
Here’s a bit of geeky plant science. On this image of the roots of white clover, you can plainly see bumps along the roots that are called nodules. Over millions of years, the plant has evolved a symbiotic relationship with certain species of soil-dwelling bacteria called Rhizobia. This group of bacteria has the ability to take nitrogen from the atmosphere and “fix” it by ...

Is Conservation Tillage the Future of Agriculture?
Like any business, farmers must manage their farms with one foot in the present and the other in the future. It’s not enough to focus just on yields. We must also consider the impact those yields have on our fields. To ensure sustainable crop production, the implementation of a method like conservation tillage is vital. Conservation tillage is a tilling process that leaves at least ...

NIR & spectroscopy in agriculture & crop science
According to a review by Dr. Crocombe, hand-held spectrometers have historically been used by only small groups of people, such as analytical and drug companies. These days, spectroscopy is available in simple low cost devices for a multitude of applications for scientists and non-scientists alike. One of the most prominent uses of spectroscopy has been the use of the technology on leaves for ...

Deer eating your plants? Tips for solving deer problems:
‘Deer’ can refer to any one of almost a hundred different species spanning the globe. The most common species in the U.S. are the white-tailed deer (in the east, southeast and Midwest) and the mule deer out west. Deer numbers have increased considerably since man has virtually eliminated their major predators. Suburbs encroaching on formerly natural open areas, woods and farm ...

KMI Zeolite: A Key Ingredient In Green Waste Compost
General statement: KMI Zeolites are 97+% pure crystalline, hydrated aluminosilicates of alkali and alkaline earth cations which possess three-dimensional crystal structures. They have the ability to lose and gain water reversibly, to adsorb molecules of appropriate cross-sectional diameter and to exchange their constituent cations (NH4+, Na+, K+, Ca2+) without major change in their structure. ...

How to Compost Pig Manure into Organic Fertiliser
In general, a 200lb pig would produce about 13lb manure per day. Pig manure contains plentiful essential nutrition ingredients like nitrogen, phosphorus and potassium for plant growth, which can promote healthy growth and increase the yield of grain crop. Even though pig manure is a commendable raw material of organic fertilizer, lots of pig manures carry E.coli, salmonella, parasitic worms and a ...

Nitrogen removal and power generation from treated municipal wastewater by its circulated irrigation for resource-saving rice cultivation
This study aims at improving the performance of the cultivating system of rice for animal feed with circulated irrigation of treated municipal wastewater by applying a larger amount of wastewater, as well as adding a microbial fuel cell (MFC) to the system. The results of bench-scale experiments indicate that this modification has increased the rice yield, achieving the target for the rice ...

Should organic certification be banned for hydroponic crops?
The USDA recommendation also includes banning aquaponics and aeroponics. The proposal would allow for some types of container production systemsthat meet the nitrogen formulas provided by the Crops Subcommittee. Aquaponics is being defined as a recirculating hydroponic plant production system in which plants are grown in nutrients originating from aquatic animal wastewater. Aeroponics is ...

Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer
The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

The oil intensity of food
Today we are an oil-based civilization, one that is totally dependent on a resource whose production will soon be falling. Since 1981, the quantity of oil extracted has exceeded new discoveries by an ever-widening margin. In 2008, the world pumped 31 billion barrels of oil but discovered fewer than 9 billion barrels of new oil. World reserves of conventional oil are in a free fall, dropping every ...
