Transition of fertilizer application and agricultural pollution loads: a case study in the Nhue-Day River basin
Rapid socio-economic development in suburban areas of developing countries has induced changes in agricultural waste and nutrient management, resulting in water pollution. The study aimed at estimating agricultural nutrient cycles and their contribution to the water environment. A material flow model of nitrogen (N) and phosphorus (P) was developed focusing on agricultural activities from ...

Corn Production in the Bowen Food Basin - Case Study
In Bowen, Queensland, in 2010, Hibrix was compared with a high NPK mineral fertiliser program for the production of maize cv. Hycorn 675IT on an alluvial sandy loam soil irrigated via sub-surface drip tape. At commercial harvest, cobs from 20 randomly selected plants per plot from were harvested, weighed and the length, girth at the cob base and length of tip not filled with kernels was measured. ...

Fine root distributions in oilseed and pulse crops
Fine roots are of great importance in the uptake of water and nutrients from, and input of, carbon to the soil. This study determined the proportion of extra fine (0.4 mm contributed a small proportion to the total. For pulses (Cicer arietinum L. chickpea, Pisum sativum L. dry pea, and Lens culinaris Medik. lentil), the proportion of roots in the 0- to 0.2-mm diameter was much smaller than that ...

Organic and mineral input management to enhance crop productivity in Central Kenya
Organic resources (ORs) are important nutrient inputs in tropical agriculture. Combined with mineral fertilizers, they form the backbone of integrated soil fertility management. This study was conducted to determine the medium- to long-term influence of OR quality and quantity on maize productivity and to evaluate the occurrence of additive benefits in terms of extra grain yield produced by the ...

Root analysis in the field: Industries & uses
Analysis of the root system is important in ensuring sustainable crop production, reducing nutrient input and irrigation, and protecting soil carbon pools. Getting rapid and frequent images of what is happening underground can help people make timely decisions about agricultural practices to maintain plant health and ensure the judicious use of resources. Root analysis can reduce financial and ...

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 ...

Understand Crop Nutrients to Optimize Farm Management
Crop Nutrient Uptake and Removal Farming today is an increasingly complex business. However, when you break down the simplest function of agriculture, it’s all about nourishment. With the global population expected to reach nearly 10 billion by mid-century, nourishing your soil to meet this demand is increasingly essential to what you do. How often does crop nutrient uptake and removal ...

Why are we monitoring nutrients at different depths?
Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

Results from the ground up
Maintaining soil health and increasing bushels Soil health is the most important aspect of your farm fields. Without healthy soil, you face a tough challenge each year. When your soil profile is strong and not deficient in any nutrients or minerals, you increase your chance of a successful growing season. More than anything, healthy soil gives you the chance to increase your bushels. If your soil ...

Let’s stop treating our soil like dirt
One of the most underappreciated resources on our planet, soil does much more than grow crops The United Nations’ International Year of Soils is hardly a media darling. Maybe it’s because many people are like me, who recall Mom’s words: “Take off your shoes! Don’t bring dirt into the house!” With all the challenges in the world today, why would we recognize ...

Evaluating cumulative effects of anthropogenic inputs in Prince Edward Island estuaries using the mummichog (Fundulus heteroclitus)
Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...
