SOIL DEGRADATION  When plants (trees & shrubs) are cleared from a site, soil is exposed to sunlight and the eroding effects of wind and water. Soil aeration.

Soil erosion or degradation is a natural process. It becomes a problem when human activity causes it to occur much faster than under natural conditions.

Department of Agriculture & Environmental Science, Lincoln University SOIL PHYSICAL PROPERTIES AS AFFECTED BY TWO YEARS OF TILLAGE, COVER CROP AND CROP ROTATION Samuel Haruna Department of Agriculture & Environmental Science, Lincoln University Advisor: Dr. Nsalambi V. Nkongolo

Outline Introduction Major Agricultural Challenges Response to Challenges Objective of Study Materials and Methods Results Summary

Introduction Study various “Treatments”. “Cropping Systems Coordinated Agricultural Project: Climate Change, Mitigation, and Adaptation in Corn-based Cropping Systems” (USDA-NIFA). Study various “Treatments”. Effects of treatments on Agricultural Production. Effects of treatments on environment.

The Challenge How to manage soils for sustainability.

Response to challenges Terrace Farming Cover Crops

Cover Crops Why use them? Nitrogen fixation. Weed suppression. Enhancing soil health (increasing infiltration, relieving compaction, addition of organic matter).

Cover Crops Why use them? Prevent soil erosion (crusting, wind erosion). Soil moisture conservation. Protect water quality (nonpoint source pollution reduction, Nitrogen leaching). Source: Modern American poetry: The Dust Bowl (www.english.illinois.edu/maps/depression/dustbowl)

Cover Crops Literature Review

Cover Crops Trends with cover crops across the corn belt (Dr. Rob Myers). 10-11% increase in corn yield. 12-14% increase in soybean yield.

Cover Crops “Cover crops lower soil temperature, thereby increasing soil water content” (Blanco- Canqui et al., 2011). Improved infiltration of rainfall in cover crop plots has been observed when compared to no cover crop plots (Folorunsho et al., 1992; Joyce et al., 2002; Williams and Weil, 2004).

TILLAGE

TILLAGE Tillage often increases bulk density partly as a result of compaction from heavy equipment (Eltaif et al., 2011; Hamza et al., 2005; Follet et al., 2009; D’Haene et al., 2008). Higher macroporosity has been found in conventional tillage compared with no-till management. (Gantzer and Anderson, 2002; Golabi et al., 1995).

OBJECTIVE OF STUDY

Objective To investigate the effects of tillage, cover crop and crop rotation management practices on soil physical properties

Study Site

Experimental Site Location: Latitude 38058’16”N and longitude 92010’53”W Soils Series: Waldron silt loam (fine, smectitic, calcareous, mesic Aeric Fluvaquents) Land Area: 4.05 ha 48 Plots

Experimental Design and Treatments Experimental Design: Randomized Complete Block (RCB). Main Crops: Corn/Soybean. Experimental treatments with three replicates: Cover crop with tillage. Cover crop with no-till. No cover crop with tillage. No cover crop with no-till. Continuous corn Continuous soybean Corn/soybean Soybean/corn

Experimental Design and Treatments Sampling: 0-10cm. 10-20cm. 20-40cm. 40-60cm.

Experimental Design and Treatments Crop Rotation (Corn / Soybean)

Summary Cover crop has the ability to improve productivity by reducing bulk density and increasing porosity. Tillage reduces productivity by increasing soil erodibility. Crop rotation can reduce pest and weed activity through allelopathy.
