Strategies for Improving the Crop Safety and Efficiency of Starter Fertilizer for Saskatchewan Crops

Crops were planted in flats of soil are prepared to simulate a seed-bed and a low-disturbance opener configuration (10% seed bed utilization). Eleven commonly grown Saskatchewan crops (wheat, barley, canary seed, flax, canola, mustard, field pea, chickpea, drybean, alfalfa, brome grass), for which tolerance to regular seed-placed P fertilization was determined in a previous 1 year ADF project, will be placed in the furrows in the soil. The treatment comparisons were be conventional 12-51-0 fertilizer versus the a polymer coated controlled release P fertilizer. Eight different rates of fertilizer were used, and treatments were be replicated six times under two different moisture regimes: high evaporative loss and low evaporative loss. Parameters measured will be emergence counts, plant biomass after one month, and phosphorus uptake. Supply rates of P will also be measured using PRS probes. Combinations of P fertilizer alone and with 15 kg K2O/ha placed in the seed-row will be evaluated to determine the tolerance and response of the crops to both P and K in the seed-row.

Overview

A series of controlled environment experiments is planned in which flats of soil are prepared to simulate a seed-bed and a low-disturbance opener configuration (10% seed bed utilization) is used to prepare furrows. Read more

Interpretive Summary

2006

Strategies for Improving the Crop Safety and Efficiency of Starter Fertilizer for Saskatchewan Crops, 2006 Questions on safe rates of seed-placed P and K fertilizer are commonly asked by crop advisers each year on the Northern Great Plains. A series of experiments on the effects of form and rate of seed-row placed P and K fertilizer were carried out under controlled environment conditions on a P-deficient soil.
