Other claims from this paper (6)
- Intervention effect P fertilizer increased grain yield in 7 of 18 site-years.
- Intervention effect Fertilized very low soil-test P soybean plots yielded similarly to high and very high plots.
- Intervention effect Fertilization of high or very high soil-test P plots did not increase yield.
- Intervention effect Applied P increased grain P removal at 14 of 18 site-years in low and medium soil-test P classes.
- Intervention effect Applied P did not increase grain P removal in high and very high P testing soils.
- Recommendation The authors conclude that building soils to high or very high STP gives no greater yield potential than adequately fertilizing low or medium testing soils.
