Silica in Agriculture

http://www.nutri-tech.com.au/blog/2010/06/silica-the-hidden-cost-of-chemicals/

Silica – The Hidden Cost of Chemicals

A major mineral is missing in many soils and most soil tests do not even monitor its presence. This mineral can increase stress resistance, boost photosynthesis and chlorophyll content, improve drought resistance, salt tolerance and soil fertility and prevent lodging. lt can also reduce insect pressure, frost damage and destructive disease while lowering irrigation rates, neutralising heavy metal toxicity and countering the negative effects of excess sodium. If I were to tell you that this same missing mineral can increase root growth, boost yield and enhance crop quality, you could well ask, “how could we have overlooked something so important?” and you would be correctIt has been a serious oversight. The mineral in question is silicon, and science is rapidly revealing the scope and scale of our silicon neglect.

Summary

Due to higher yields, commodity prices and crop input costs, growers are reviewing all potential barriers to top grain production, including micronutrient deficiencies.
In the major crops and production areas of North America, the micronutrients most often supplied by fertilization include zinc, manganese, boron and iron.

Micronutrient deficiencies can be detected by visual symptoms on crops and by testing soils and plant tissues.

The most reliable micronutrient soil tests are for zinc, boron, copper, and manganese. Though adequate, these tests are not as precise as those for soil pH, potassium and phosphorus.

Plant tissue analysis is more reliable than soil testing for identifying many micronutrient problems, and can also supplement soil test information.

Most often, micronutrients are soil-applied in a band at planting, or foliar-applied, as these methods allow lower use rates of sometimes expensive materials.

Silicon in plant and soil

http://www.silicon-nutrition.info/Silicon_in_plants_and_soil.html

Silicon in plant and soil


Silicon protects plants from stress. Benefits of the nutrient especially become evident in adverse situations. While it is so difficult to prove the essentiality of silicon, experts often call the element 'beneficial' or even 'quasi-essential'.
As a rule of thumb cereals and other monocotyledonous crops rank as silicon accumulators and dicotyledonous plants are non-accumulators. On hydroponics however, several dicotyledonous pot plants, cut flowers and vegetable crops benefit from silicon fertilisation.




Soluble silicon in soil solution is at a pH range from 2 to 9 mainly present as orthosilicate. In this form silicon is an uncharged compound and is sensitive to leaching. Although sandy soils are silicon-rich, soluble silicon content is usually very low. Apart from rice products containing potting soils, growing media for pot plant and woody ornamentals are often poor in silicon.

Sericulture in the CĂ©vennes: from a first visit, autumn 2010

"Prof.Simon Charsley’s name evokes mixed feelings of respect, admiration and affection in our minds."

"Professor Charsley spent his prime years in India, and took up study on a topic which would have appeared rather unfashionable to the contemporary intelligentsia. His introduction to Indian Sericulture was quite accidental. In his own words”... I first came to India on a Younger Scientist exchange programme and found sericulture in Mysore. The enthusiasm that I met led me to a research project on the silk industry and how it worked in practice, and also to many good friends....” That was in the mid seventies- an era marked by rapid modernisation of Indian sericulture sector. The result of his intensive study of the rural livelihood was the classic “Culture and Sericulture (1982)” which still remains one of the most authentic documentations on Indian sericulture and probably the only one comparable to the work of Lefroy and Ansorge (1915), though different in perspective and purpose. Subsequently he wrote a number of papers practically covering every aspect of the industry viz.regulated markets, middlemen, technology, silk reeling etc. which still remain most valuble reference material for students of respective disciplines.

Indian sericulture is indebted to Prof. Charsley, primarily for bringing it into the contemporary developmental rhetoric. He was the first and (unfortunately) the last to address sericulture as a livestock industry. Probably its scope of being so designated is largely under-estimated by the academics and policy makers. Prof. Charsley argued that sericulture shares much with and historically has led the way for other livestock industries and advocated its importance in the developmental context. His view of sericulture- as a ‘study material’ in social and anthropological assessment of development in a society where people are separated not only by status, culture and life circumstances but also by religion caste and politics is still highly relevant.

Micro Nutrient Foliar Sprays in UK

http://www.fwi.co.uk/Articles/30/03/2012/132191/Philip-Bradshaw-ponders-the-value-of-micro-nutrients.htm

Philip Bradshaw ponders the value of micro-nutrients


"To improve oilseed yields, we apply various micro nutrients through the growing season."

...

"It was while considering the use of foliar-applied nutrients that a thought occurred. ..
Are all the micro nutrient products the same quality, are some better than others? Do they differ in efficiency of uptake and how compatible are they?"

...

"However, I remain surprised that we do not as an industry consider the foliar nutrition products on offer , and how we apply them, in more depth."

Philip Bradshaw grows cereals, sugar beet and potatoes on 300 ha of fenland and other soil types at Flegcroft Farm, Whittlesey, Cambridgeshire.

Global Cropland

With seven billion people now living on Earth, the ever growing demand is putting unprecedented pressure on global resources—especially forests, water, and food. How can Earth’s resources be managed best to support so many people? One key is tracking the sum of what is available, and perhaps nothing is better suited to that task than satellites.

These two images show food production on both a global scale and a landscape scale. Made with data from the Moderate Resolution Imaging Spectroradiometer (MODIS), the top image shows where crops are grown throughout the world. Green areas are cropland, while tan areas are other types of land cover. In the last 40 years, cropland has increased by 70 percent to feed a growing population. Crops now cover about 40 percent of Earth’s land.

The lower image provides a landscape scale view of farming. The Landsat 7 satellite acquired the natural-color image on July 31, 2002. Bright green and gold fields stand out in stark contrast to the arid landscape along the Columbia River in western Washington. At this scale it is possible to gauge how healthy a crop is and estimate how much food it might produce. The United States Department of Agriculture uses such satellite data extensively to help determine where, when, and which crops are planted each year. They also use it to predict yields and to make commodity forecasts.

Measurements from the Landsat satellite also make it possible to tell how much water the crops consume in an arid environment. Such measurements are likely to become more important as demands on limited water resources increase. Currently, agriculture accounts for 85 percent of the world’s fresh water consumption.

“What we’ve done with satellites over the past 40 years is revolutionize how we monitor agriculture, forests, fresh water consumption, and other Earth resources required by the global population,” said James Irons, Landsat project scientist at NASA’s Goddard Space Flight Center. The worldwide pressure of feeding everyone requires a tool that has an impartial, world-wide view, making satellites a unique resource for scientists and policymakers alike.
