Organic amendment history and crop rotation effects on soil Nitrogen mineralization potential and soil Nitrogen supply in a potato cropping system
Crop management practices influence readily and potentially available N in soil. In this study, we evaluated the effects of organic amendment history and crop rotation on potentially mineralizable N (N0), mineralizable N pools, and field estimates of soil N supply in potato (Solanum tuberosum L.) production, and evaluated a suite of N availability measures to detect changes in these parameters. ...

Influence of rainfall interception by endemic plants versus short cycle crops on water infiltration in high altitude ecosystems of Ecuador
Owing to their high water retention, the volcanic ash-soils of the Northern Andean highlands (páramos) can be considered as natural ‘water storage tanks’ for drinking water and for irrigation. Vegetation plays an important role in transferring rain to the soil and in controlling the soil water content. To assess this role, we quantified the stemflow process under rainfall simulations for ...

4 tips for successful potato establishment this spring
Alistair Neill, a Prime Agriculture potato agronomist based in Norfolk, shares his four essential tips on getting potato crops off to the best start possible, beginning with ensuring good crop establishment.1. Cut back on cultivations Soil compaction can jeopardise potato establishment and yield because it restricts root growth, consequently limiting water and nutrient uptake. Therefore, if it’s ...

How to Increase Potato Tuber Size and Yield
The main challenge for farmers at the end of the tuber initiation phase is to achieve a high number of tubers above 15 mm. Any tubers that do not reach this size shrink and disappear. The main challenge after the tuber initiation phase is to optimise the reserves and obtain a maximum of marketable ...

Farmonaut For Crop Area and Yield Estimation
INTRODUCTION: CROP AREA ESTIMATION The two components of agricultural production estimation are crop area and yield estimation. In order to estimate yield, Producers generally measure the amount of a particular crop harvested in a sample area to estimate crop yield. The harvested crop is then weighed, and the entire crop production of the area is approximated from the sample. A method for ...

What is it about this soil that protects plants from devastating disease?
Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

Comparative mycotoxin profiles of gibberella zeae populations from barley, wheat, potatoes, and sugar beets
Gibberella zeae is one of the most devastating pathogens of barley and wheat in the United States. The fungus also infects noncereal crops, such as potatoes and sugar beets, and the genetic relationships among barley, wheat, potato, and sugar beet isolates indicate high levels of similarity. However, little is known about the toxigenic potential of G. zeae isolates from potatoes and sugar ...

Seasonal slug pressure warning – crops at greater risk
Crops face a greater risk of slug damage and if left untreated, this can become extremely expensive for farmers, and is estimated to cost the potato industry up to £53 million per year*, as any slug damage reduces saleability and ultimately profitability of a crop. Slugs are most damaging to potatoes during the early stages of tuber bulking, which is starting to happen now. So make sure ...

What’s your potato storage strategy?
With potato harvest nearing completion, the challenge will now be to maintain the condition of the crop, right up until supply to the customer. “It’s really worth stopping to consider that what you put into storage, is reflective of what you get out post-storage,” explains Morley Benson of Certis. “By this, I mean the quality of potatoes going into store, as well as the ...
