Relationship between subsoil nitrogen availability and sugarbeet processing quality
The loss of sugar content and processing quality during the harvest period happens frequently in sugarbeet (Beta vulgaris L. ssp. vulgaris) grown in the Po Valley of Italy. The aim of this study was to assess the consequences on sugar content and quality of excess mineral N in the deep soil explored by the roots. Soil mineral N concentration and other chemical properties to a 3-m depth were ...

Fertilization management of paddy fields in Piedmont (NW Italy) and its effects on the soil and water quality
The fertilization management of the rice crop in Piedmont was analyzed at a regional scale, and the agronomic and environmental sustainability of the actual fertilization strategy of rice was evaluated through the analysis of its effect on the soils and waters quality. On average, a total amount of 127 kg ha − 1 of N, 67 kg ha − 1 of P 2 O 5 and 161 kg ha − 1 of K 2 O were ...

Recovery of residual fertilizer-nitrogen by wheat in a winter wheat–summer maize rotation in the north china plain: A soil column study
Cropping systems is potentially useful practice for mitigating nitrate leaching and increasing nitrogen use efficiency (NUE) because deeper rooted crops could capture the leached N from previous shallower rooted crops. The recovery of fertilizer nitrogen (FN) applied to maize (Zea mays L.) by the succeeding wheat (Triticum aestivum L.) in a winter wheat–summer maize rotation in North China Plain ...

Corn grain yields and yield stability in four long-term cropping systems
Most long-term studies evaluate only average crop yields and overlook year-to-year yield variability, which could be highly significant. Our objectives were to evaluate the impact of long-term cropping systems and fertility management on corn (Zea mays L.) yield and yield stability. Cropping systems were (i) CC, continuous corn; (ii) CS, corn-soybean [Glycine max (L) Merr.]; (iii) 4C4A, 4 yr ...

Simulation of soil carbon dynamics under sugarcane with the CENTURY model
Currently there is a trend for the expansion of the area cropped with sugarcane (Saccharum officinarum L.), driven by an increase in the world demand for biofuels, due to economical, environmental, and geopolitical issues. Although sugarcane is traditionally harvested by burning dried leaves and tops, the unburned, mechanized harvest has been progressively adopted. The use of process based models ...

Extension workers' attitude towards usefulness of an integrated soil fertility and nutrient management approach in Bangladesh
The main focus of this study was to determine extension workers' attitude towards usefulness of Integrated Soil Fertility (ISF) and Nutrient Management (NM) approach for sustainable crop production. Data were collected from 64 extension workers from four districts in Bangladesh using face-to-face interview from December 2005 to January 2006. Findings indicated that more than two-thirds (68%) of ...

Why doesn`t fruit have a good color?
There are Five factors Temperature affacts coloring. Low temperature promotes the formation of anthocyanins, while high temperature has the opposite inhibitory effect, which is why fruit trees often appear in producing areas with high temperature for a long time during the coloring period, where the fruit is very sweet and the fruit is ripe, but its color has not yet reached the standard for ...

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 ...

Sequence analysis of dssat to select optimum strategy of crop residue and nitrogen for sustainable rice-wheat rotation
Weather variability affects the production of most cropping systems, and rice (Oryza sativa L.)-wheat (Triticum aestivum L.) rotation is not an exception. Integrating weather forecasts with soil fertility management options is one way to combat the production decrease by anticipating weather variability along with sustaining the soil environment. Sequence analysis of DSSAT3.5 was used to select ...

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 ...

Interactive effects of tillage and mineral fertilization on soil carbon profiles
Both tillage and fertilizer management influence soil organic C (SOC) storage, but their interactive effects remain to be determined for various soil and climatic conditions. We evaluated the long-term effects of tillage (no-till, NT, and moldboard plowing, MP), and N and P fertilization on SOC stocks and concentrations in profiles of a clay loam soil (clayey, mixed, mesic Typic Humaquept). Corn ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...

How to Improve Apple Conservation by Reducing Bitter Pit
Bitter Pit is a physiological disorder, linked to a calcium deficiency in apples. Symptoms: dark brown or black lesions, results of the breakdown of the cells under the skin, appear on the skin of the fruit only after harvest. Calcium is not very mobile within the trees. Even though soil and leaves are correctly fed with this element, a deficiency can appear on fruits. This is especially true ...

From One Ag Leader to Another: Harvest
Think about this: as a farmer, you only get one shot at harvesting your crop each year. Now think about how many things have changed in the past 10 or 20 years: bigger, faster and more accurate equipment, new seed technologies, better herbicide, insecticide and fertilizer options, improved water management, precision technologies … the list goes on. The first time you tried some of these ...

Phosphorus runoff from turfgrass as affected by phosphorus fertilization and clipping management
Received for publication December 8, 2008. Phosphorus enrichment of surface water is a concern in many urban watersheds. A 3-yr study on a silt loam soil with 5% slope and high soil test P (27 mg kg–1 Bray P1) was conducted to evaluate P fertilization and clipping management effects on P runoff from turfgrass (Poa pratensis L.) under frozen and nonfrozen conditions. Four fertilizer treatments ...

Enhancing phosphorus phytoremedation potential of two warm-season perennial grasses with nitrogen fertilization
Phytoremediation or use of plants to extract soil nutrients is a practice used to ameliorate the impacts of excessive soil nutrients. Pensacola bahiagrass (Paspalum notatum Flügge) and ‘Floralta’ limpograss [Hemarthria altissima (Poir.) Stapf & Hubb] were grown in a P-impacted Immokalee fine sand (Mehlich-1 P 30 mg P kg–1) to evaluate increasing N levels on dry matter yield (DMY), forage P ...

Evaluation of in-season Nitrogen management strategies for corn production
Nitrogen is an important and costly input for corn (Zea mays L.) production. With rising prices and environmental concerns, producers are looking for ways to better manage N fertilization. A project designed to evaluate in-season N management strategies for adjusting N rate was conducted in 30 Iowa cornfields from 2004 to 2006. Nitrogen rates applied preplant or early sidedress (PRE-N) and corn ...
