Soil carbon levels in irrigated western corn belt rotations
Proposals promoting the use of massive amounts of crop residues and other lignocellulosic biomass for biofuel production have increased the need for evaluation of the sustainability of cropping practices and their effect on environment quality. Our objective was to evaluate the effects of crop rotation and N fertilizer management and their stover production characteristics on soil organic carbon ...

Transition from intensive tillage to no-tillage and organic diversified annual cropping systems
Transition to no-till (NT) and organic (ORG) farming systems may enhance sustainability. Our objectives were to compare transitional crop productivity and soil nutrient status among diversified NT and ORG cropping systems in Montana. Three NT systems were designed as 4-yr rotations, including a pulse (lentil [Lens culinaris Medik.] or pea [Pisum sativum L.]), an oilseed (canola [Brassica napus ...

Broiler litter fertilization and cropping system impacts on soil properties
Understanding the effects of management practices on soil properties is necessary because soil properties are directly related to the capacity of soil to function. Soil physical, chemical and biological properties were determined after 3 yr in three cropping sequences [continuous cotton (Gossypium hirsutum L.) (CCC), cotton-corn (Zea mays L.)-cotton (CMC), and corn-cotton-cotton (MCC) each at ...

Don`t forget water in the true cost of biobased packaging
The additional 3 billion middle-class consumers expected by 2030 presents one of today’s greatest challenges, but they also provide one of the business community’s greatest financial opportunities. Against the backdrop of an increasingly resource-constrained world and volatile commodity prices, business as usual is not an option. The scalable, resource-efficient business models of ...

High-Yielding corn response to applied Phosphorus, Potassium, and Sulfur in Nebraska
Nutrient management recommendations may change as yield levels and efficiency of crop production increase. Recommendations for P, K, and S were evaluated using results from 34 irrigated corn (Zea mays L.) trials conducted in diverse situations across Nebraska. The mean yield was 14.7 Mg ha–1 with adequate fertilizer applied. The median harvest index values were 0.52, 0.89, 0.15, and 0.56 for ...

Living mulch forage yield and botanical composition in a corn-soybean-forage rotation
Managing forages as living mulches during row crop production requires suppressing the forages to produce economical crop yields. The objective of this research was to identify forage plants with varied growth habit, persistence, and yield potential to provide desirable ecosystem functions in a multifunctional cropping system. Alfalfa (Medicago sativa L.), kura clover (Trifolium ambiguum Bieb.), ...

The manage database: nutrient load and site characteristic updates and runoff concentration data
The 'Measured Annual Nutrient loads from AGricultural Environments' (MANAGE) database was developed to be a readily accessible, easily queried database of site characteristic and field-scale nutrient export data. The original version of MANAGE, which drew heavily from an early 1980s compilation of nutrient export data, created an electronic database with nutrient load data and corresponding site ...

Effects of changes in climatic variables on maize crop water requirements in Huang–Huai–Hai watersheds, China
The study of crop water requirements (CWR) under climate change is critical for reasonable crop irrigation. In the present study, the effects of changes in climatic variables from 1961 to 2010 on maize CWR in Huang–Huai–Hai (HHH) watersheds in China were investigated. Five daily climatic factors including maximum temperature (Tmax), minimum temperature (Tmin), wind speed (u2), ...

Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China
Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...

Side-band injection of acidified cattle slurry as starter P-fertilization for maize seedlings
Abstract Accumulation of phosphorus (P) in agricultural soils has caused increasing environmental concerns. Maize cropped for fodder implies return of animal manures rich in nutrients. In addition, starter fertilization with mineral P is used in cold conditions for maize cropping. It was hypothesized that the use of the additional mineral P could be excluded by increased availability of the P ...

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. ...

Long-term fertilizer experiment network in China: Crop yields and soil nutrient trends
Results are summarized for the first 15 yr of an eight-site, long-term experimental network in China designed to assess the sustainability of cropping systems in environments representing 70% of Chinese cropland. Systems were wheat–maize double cropping (two crops per year) at four sites, wheat–rice double cropping, rice-based triple cropping, and wheat or maize single cropping. Without ...

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 ...

Cover Crop and nitrogen effects on maize productivity in no-tillage systems of the Brazilian Cerrados
Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...

Climate change to worsen drought, diminish corn yields in Africa
Original story at MIT News Nearly 25 percent of the world’s malnourished population lives in sub-Saharan Africa, where more than 300 million people depend on corn, or maize, as their main food source. Maize is the most widely harvested agricultural product in Africa and is grown by small farmers who rely heavily on rainwater rather than irrigation. The crop is therefore extremely sensitive ...

Corn grain yield response to crop rotation and nitrogen over 35 years
Crop rotation and N are management methods that can increase corn (Zea mays L.) grain yields. Our objective was to determine the corn grain yield response to six crop rotation sequences and four N rates in a long-term (35-yr) study. The rotations were continuous corn (CC), corn–alfalfa (Medicago sativa L.) (CA), corn–soybean [Glycine max (L.) Merr.] (CS), corn-corn-corn-alfalfa-alfalfa (CCCAA), ...

Improve Fall Nitrogen Practices
In most of the US, this fall was a wet one. Chances are, you didn’t get much of a chance to get fall anhydrous in the ground. Beacuse of this, we wanted our agronomist, Barry Anderson, to answer a few of our burning questions related to fall nitrogen application. You may have missed the window this year, but here are some tips to keep in mind for next year. 1. At what rate/ ...
