Maharjan Lab

Maharjan Soils Lab is part of the University of Nebraska-Lincoln Panhandle Research, Extension and Education Center in Scottsbluff. The lab integrates research, extension, and education on soil health and fertility, nutrient management, soil carbon, and practical strategies that improve farm productivity while protecting water and air quality.

Five questions a funder or collaborator asks

What it studies, who does it, where, what it found, and who funds it.

Sources and limits for these answers

Each answer says what it is built from. Public records answer part of each question; the organization's own project and member lists complete it.

What it studies
6 themes across the 5 records in this view, 2020–2026 Soil Health appears most often (4 records).
Who does the work
Counted from the author lists of the 5 records in this view; authors include outside collaborators Completes it: The group's own member list, so members and outside collaborators read apart.
Where the work happens
1 county · 1 state; sites read from methods sections
What it found
From 3 sources among 8 outputs, each quoted from its source; not yet checked by a reviewer Completes it: Readable full text for the remaining papers, so their findings can be extracted.
Who funds it
From the funding statements of 3 of the 5 records in this view; a statement names a funder, not an amount USDA-NRCS is named most often (2 records). Completes it: The group's own award list, with amounts and years.

Summaries from the research index

These takeaways are a starting point. They do not replace reviewed measurements, methods or institutional attribution.

Indexed research summary

Effect of fertilizer nitrogen on biomass yield and nitrous oxide gas emissions in peppermint in Nebraska

Polymer Coated Urea (PCU) improves mint yield and also reduces nitrous oxide emission

Indexed research summary

Soil health assessment across paired cropland and reference sites under diverse edaphic and climatic conditions

Croplands at sites with manuring and no-till recorded lower soil organic matter depletion from reference-site levels (28%) than sites under continued conventional management.

Indexed research summary

Soil health cycle

The soil health cycle is proposed as a soil health management cycle encompassing human dimensions, management practices, and their effects on soil health indicators, leading to subsequent impacts on soil functions.

What the measurements showed
