Developing Nitrogen fertilizer recommendations for corn using an active sensor
Producers often overapply N fertilizer to corn (Zea mays L.) because of the uncertainty in predicting the economic optimum nitrogen rate (EONR). Remote sensing represents a potential opportunity to reduce this uncertainty with an in-season assessment of crop N status. This study examines the relationship between EONR and reflectance from a ground-based sensor, and considers its potential for ...

Knowledge is power: A day in the life of a soil consultant
This week we talk with Amy Duckworth from Soil Matters Over time the agriculture sector has become more efficient and we are more equipped to measure and manage with a higher level of accuracy. Amy recognizes the importance of measuring what we manage — to reach new levels of efficiency. As a soil consultant, Amy is often involved in ‘on-farm’ decision making around fertilizer ...

Direct steam distillation as an alternative to the illinois soil nitrogen test
Development of the Illinois Soil N Test (ISNT) has rejuvenated the search for a soil-based N test to measure potentially mineralizable soil N. Accurate quantification of amino sugar N has been achieved using the ISNT, but issues concerning sample variability and analysis time have led to the discovery of a 10 mol L–1 NaOH direct steam distillation (DSD) procedure. Our primary objective was to ...

Aerial color infrared photography to optimize in-season nitrogen fertilizer recommendations in winter wheat
Remote sensing in the form of aerial color infrared (CIR) photography has been shown to be a useful tool for in-season N management in winter wheat (Triticum aestivum L.). The objectives of this study were (i) to develop a methodology for predicting in-season optimum fertilizer N rates for winter wheat at growth stage (GS) 30 directly from aerial CIR photography and (ii) to quantify how the ...

Strategies to make use of plant sensors-based diagnostic information for nitrogen recommendations
Improvements of nitrogen use efficiency (NUE) may be achieved through the use of sensing tools for N status determination. Leaf and canopy chlorophyll, as well as leaf polyphenolics concentrations, are characteristics strongly affected by N availability that are often used as a surrogate to direct plant N status estimation. Approaches with near-term operational sensors, handheld and ...

Sensitivity of chlorophyll meters for diagnosing nitrogen deficiencies of corn in production agriculture
Chlorophyll meters have been widely used to diagnose N deficiencies in research trials and to help refine N fertilizer recommendations in production agriculture. The diagnoses are based on the assumption that chlorophyll meters can detect a wide range of N deficiencies under field conditions according to relationships between chlorophyll meter readings (CMRs) and yield responses to N ...

Nutrient dynamics from broiler litter applied to no-till cotton in an upland soil
Applying broiler litter to the soil surface of a no-till field of cotton (Gossypium hirsutum L.) increases the potential loss of its nutrients via runoff and volatilization. An experiment was conducted over 3 yr on an upland Atwood silt loam soil (fine-silty, mixed, semiactive, thermic Typic Paleudalfs) near Pontotoc, MS, to determine the effect of broiler litter incorporation into the surface ...

Nitrogen fertilization effect on phosphorus remediation potential of three perennial warm-season forages
Warm-season C4 grasses are capable of removing excess soil nutrients because of their high yield potential and nutrient uptake efficiency. Bahiagrass (Paspalum notatum Flügge), limpograss [Hemarthria altissima (Poir.) Stapf & Hubb], and stargrass (Cynodon nlemfuensis Vanderyst), three commonly used pasture grasses in South-Central Florida, were grown to examine the effect of increasing N ...

Rainfall simulation in greenhouse microcosms to assess bacterial-associated runoff from land-applied poultry litter
Runoff water following a rain event is one possible source of environmental contamination after a manure application. This greenhouse study used a rainfall simulator to determine bacterial-associated runoff from troughs of common bermudagrass [Cynodon dactylon (L.) Pers.] that were treated with P-based, N-based, and N plus lime rates of poultry (Gallus gallus) litter, recommended inorganic ...

Advantages of granulation processing with flat die pellet mill
Multi-functional flat die pellet mill can produce cylindrical particles, granular feed and organic fertilizer. The machine can also be connected with polishing equipment, so that the cylindrical particles can be rolled into balls at one time without returning particles. It often is used in organic fertilizer production line, and which is an ideal equipment for feed processing particles. ...

One crop, two ways, multiple benefits
Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

Crop productivity and economics during the transition to alternative cropping systems
Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop production. This study examined crop yields, input costs, and economic returns during the transition to a range of cropping system alternatives in the northern Corn Belt region, including different system ...

Biocontrol: How Strawberry Growers are leading the way
According to Dr. Surendra Dara of the University of California Cooperative Extension, 90-95% of strawberry growers in California use predatory mites to manage two-spotted spider mites. But how did this pest control method get so widely adopted? What can growers of other crops learn from this experience? To discuss this topic, I reached out to Lane Stoeckle, a certified crop advisor and pest ...

The mineralization of nitrogen from compost in the tropics
The application of organic matter is very important in maintaining high and stable crop yields under tropical conditions. Most of tropical soils are characterised by low content of organic matter and low structure stability. Animal wastes contain many nutrients, including nitrogen, phosphorous, potassium and other minerals. In addition to supplying nutrients, the application of animal wastes also ...

How to use organic fertilizer equipment to improve soil environment
Soil fertility has a great impact on crop yield and economic benefits. Soil fertility has declined and harvest has decreased, resulting in agricultural losses. Huaqiang equipment factory provides a complete set of professional organic fertilizer production equipment to help improve the agricultural soil environment. Three main reasons for the decline of soil fertility 1. The local land ...

Indoor fermentation tank is recommended for organic fertilizer production
It is recommended that the indoor trough fermentation of manure is more environmentally friendly for organic fertilizer production. How to produce fertilizer? From manure to organic fertilizer, the price has increased a hundred times, the key is to add fermentation bacteria to do fermentation treatment. Here is a brief introduction to the method of making organic fertilizer from manure and straw. ...

Effect of deficit irrigation and fertilization on cucumber
Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

Furfural residue fermented organic fertilizer-3 points you must know
Furfural residue is a kind of waste after extracting furfural from corn cob, oat and wheat bran, sawdust and other agricultural by-products. It also contains more lignin, semi lignin, cellulose and other organic components. These wastes can be transformed into organic fertilizer for plant growth by using organic fertilizer production equip​ment. Compared with other fermented ...

How to maintain soil fertility
In order to maintain soil fertility, some low-yield soil (acid soil, alkali soil and salt soil), chemical improvers and irrigation should be used to improve, remove obstacles and improve the fertility level. In addition, reasonable cultivation and rotation should be carried out to regulate the nutrients and water in the soil and prevent some nutrient deficiency and water vapor imbalance. 1. ...
