Nitrogen management, especially when compared across di eren t tillage systems, has the potential to impact corn pr oduction. e importance of N management on corn. tion tillage and conventional tillage systems require about the same quantity of nitrogen to produce a crop. Efficient nitrogen (N) management in conservation tillage corn production (particularly no-till) has been of concern to producers since the early s. It was then researchers first demonstrated that different N management programs.
There are several challenges in managing continuous corn as far as tillage is concerned. Residue management, seed placement, nitrogen (N) application, and equipment attachments are a few of the challenges to consider. Residue presents management problems, particularly with conservation tillage and no-tillage used in continuous corn production. Conservation Tillage "Any tillage and planting system that covers [an area of] soil surface with crop residue, after planting, to reduce soil erosion Two key factors influencing crop residue are (1) the type of crop, which establishes the initial residue amount and its fragility, and (2) the type of tillage operations prior to and including.
The tillage system did not affect any of the parameters studied. Water use efficiency (WUE) ranged from 5 to 14 kg ha-1 mm Wheat and sunflower as preceding crops yielded poorer values for productivity and water utilization, while the best results were obtained with faba bean.

The focus is on corn production; however, many of the management practices can be applied to grain sorghum, wheat or other crops requiring nitrogen in no-till systems. Nitrogen changes in no-till systems. Without annual mixing of the soil and crop residue by tillage, no-till systems accumulate a layer of crop residues on the soil surface.
Since there is little vertical mixing of the nitrogen in conservation tillage systems, the acidity formed when these materials react with the soil will stay near the soil surface, resulting in a lower soil pH near the surface.
Table 1 shows the effect of surface acidification when no-till corn was fertilized with liquid nitrogen for several years. Tillage systems are often classified by the amount of surface residue left on the soil surface. Conservation tillage systems leave more than 30% of the soil surface covered with crop residue.
This amount of surface residue cover is considered to be at a level where erosion is significantly reduced (see figure ). Of course, this residue.
The effectiveness of a conservation tillage system depends on the amount and distribution of plant residues left on the soil surface.

Fageria, A. Moreira, in Advances in Agronomy, 11 Root Growth in Conservation Tillage Systems. Conservation tillage is defined as any tillage sequence, the object of which is to minimize or reduce loss Nitrogen management in conservation tillage systems for corn book soil and water; operationally, a tillage or tillage and planting combination that leaves a 30% or greater cover of crop residue on the surface (Soil Science Society of America, ).
The book takes an agricultural systems approach to understanding conservation tillage systems, recognizing that the different components of conservation tillage systems are interrelated. It includes chapters on the management of cover crops, water, nutrients, weeds, insect pests and nematodes, as well as crop selection and rotation, livestock.

Mahdi Al-Kaisi is a professor of agronomy and extension soil and water specialist at Iowa State University. His current research and extension in soil management and environment focuses on the effects of crop rotation, tillage systems, residue management, and nitrogen input on soil carbon dynamic.
Missouri research has shown a 25 bushels per acre yield penalty when solution is broadcast in no-till corn (average of 20 experiments, mostly corn-soybean rotation). In other conservation tillage systems with less residue, less yield loss would be expected.
Dribbling solution reduces contact between nitrogen and residue, and injection is best. Gicheru, P., Gachene, C., Mbuvi, J. & Mare, E. Effects of soil management practices and tillage systems on surface soil water conservation and crust formation on a.

Nutrient management. Nitrogen and phospho rus are the two macronutrients most likely to be lost from cropping systems. Cover crops help reduce losses of these nutrients by.
The nitrogen required for corn should be placed below crop residues. In high residue situations coulters may be necessary for proper placement.

ing fertility management with conservation tillage has been conducted in other states with corn as the primary crop (Moschler and Martens, ; Legg et al. R.L. Blevins, W.W. Frye, in Advances in Agronomy, C SOIL ORGANIC MATTER.
When conservation tillage and conventional tillage are compared under similar conditions, conservation tillage, especially no-tillage, results in soils having higher soil organic matter contents after a few years.
That is not to say that conservation tillage always increases the soil organic matter content of soil. Practices.

The spring weather conditions have complicated nitrogen management. Much residual nitrate-N and applied fertilizer-N was likely lost to leaching and denitrification.
Other fertilizer-N was never applied due to spring rains. This summer there will need to be more in-season N application than usual and the in-field variability may be greater than usual. Progress 07/01/02 to 06/30/05 Outputs Dryland corn acreage in western Kansas has rapidly increased during the past decade, with the majority of the dryland corn grown using no-tillage practices to optimize water conservation.
However, there is limited information available on N management for no-till crop production in western Kansas, with no current information for dryland corn. Tillage System, Fertilizer Nitrogen Rate, and Timing Effect on Corn Yields in the Texas Blackland Prairie H.
