Pesticide applicators should visit the Bulletins Live! Two website to determine if they are located within a pesticide-restricted or limited area, known as a pesticide use limitation area (PULA). These restrictions protect endangered and threatened species from adverse effects. This publication provides users a step-by-step guide on how to navigate this website and access the information needed for applications and recordkeeping.

Systems Thinking Mindset
The textbook definition of a system is “an interconnected set of elements that is coherently organized in a way that achieves something.” In other words, systems thinking is a way of examining the interconnections between elements, including both the direct and indirect effects. This publication provides an overview of key concepts associated with systems, including elements, interconnections, and functions. Developing a systems thinking mindset is helpful in moving beyond simple cause-and-effect thinking to consider the patterns and characteristics of systems as well.

Soil pH is an important chemical property because it influences the availability of soil nutrients for plant uptake, and it affects a crop’s root system development. Soil pH also indicates whether lime is needed to correct toxicities caused by aluminum and manganese, or to increase calcium levels in the soil. A new method measures the buffering capacity directly.

Oat okara, the nutritious byproduct of oat milk processing, is rich in protein and dietary fiber. Current practices often discard okara or use it as animal feed. Produced in large quantities, it represents not only a sustainability challenge but also a significant economic opportunity. With potential applications in food fortification and as a cost-effective ingredient in baked goods, snacks, and more, utilizing oat okara can reduce waste and add value to the production chain. Unlocking its potential benefits both the environment and the food industry.

There are many ways to define what it means to be sustainable. There is increased demand for agricultural production transparency to ensure that food and fiber products are being produced sustainably. To this end, Field to Market: Alliance for Sustainable Agriculture has developed the Fieldprint Calculator through the Fieldprint Platform to help farmers of major commodity crops measure their on-farm sustainability by entering in their yearly management practices. This Extension publication defines sustainability, describes the use of the Fieldprint Calculator, and explains how growers can use this program to measure sustainable progress made on their farms. This publication was produced in collaboration with the University of Tennessee and Field to Market.

Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process, calcium carbonate is formed.

This bulletin provides the general public a quick reference for some commonly used standards for metal concentrations in biosolids and various by-products intended for land application. Most of the standards presented here are regulatory; however, we have also included information on average metal concentrations in agricultural soils.
