Measuring the Nutrient Accumulation Rates of High-Yielding Potatoes and Sugar Beets

IPNI-2013-USA-ID13

Overview Related

There is a lack of information on the rate of nutrient accumulation during the growing season of important Idaho crops. This project will undertake intensive plant sampling from an existing long-term soil fertility experiment. Using an on-going research site will greatly reduce the cost of the research. The plant samples will be taken from the fully fertilized experimental plots. Read more

Interpretive Summary

2017

In-season accumulation and partitioning of dry matter, macro- and micro-nutrients by glyphosate-resistant sugar beet (Beta vulgaris L. ) varieties in irrigated production systems are not well understood.

One of the fundamental components of 4R Nutrient Stewardship is applying nutrients at the "Right Time. " However, for many important crops, there is a lack of understanding of when nutrients are actually taken up during the season. A study was conducted to evaluate the amount, rate, and the partitioning of dry matter and nutrient accumulation by sugar beet during the growing season.

2015

One important aspect of 4R Nutrient Stewardship is applying fertilizer at the right time. This study with the University of Idaho was designed to measure the accumulation of nutrients in the tops and roots of sugarbeets during the growing season. Samples of leaves and roots were taken every 16 days between June and the October harvest. Harvested plants were partitioned, weighed, and their chemical composition analyzed to determine seasonal nutrient accumulation patterns.

2014

To better achieve the objective of the "Right Time" of 4R Nutrient Stewardship, the nutrient accumulation patterns are being measured in key Idaho crops. In 2014, sugar beets were grown at the ARS Kimberly Idaho Research Station. Beet samples were taken from four randomized replicated plots that received fertilizer applications based on University of Idaho recommendations. Both beet roots and beet tops were collected at 16-day intervals between June 9th to October 1st, 2014.
