Managing the Crop

When can fertilizer be applied?

Starter Fertilizer – at planting time Side Dressing – after plants have emerged

Top Dressing – after plants are established

Why is soil pH important in crop production?

Crops grow & produce the best in a pH range of 5.0 to 7.5

Soil pH affects the availability of nutrients for plant uptake

What two ways can soil pH be altered?

Application of lime reduces soil acidity Application of sulfur will reduce alkalinity

How should plant residue be managed?

Mixed/Tilled into the soil to provide organic matter

Left on the field to reduce soil erosion due to wind & water

How can plant pests be controlled?

Mechanical Cultural Biological Genetic Chemical

What irrigation methods are used in crop production

Aerial sprinkler systems (Center Pivot)

Surface (flood, drip, furrow)
