Measuring water chemistry prior to feeding will help the farmer gauge the likelihood that fish are stressed. Sick and stressed fish will not eat feed and should not be fed in order to avoid water quality issues and mortality. Visually inspecting fish for external signs of disease such as lesions, discolored skin, and erratic swimming behavior should be done to prevent feeding stressed fish. If the water quality falls within the optimal range and fish appear to be disease free, the farmer should begin feeding by hand a small portion (handful) of the feed that the fish have been rationed.
This 4-H project is designed to help you explore the world of science, engineering, and technology. Science is a way for us to look at and try to understand the world around us. Being scientific involves being curious, observing, asking questions about how things happen and learning how to discover answers. Be a part of the future! Challenge your mind by exploring the world around you with hands-on science experiments and solve problems using engineering design principles and the latest technology. The sky’s the limit - design a robot to clean your room, test a local stream for pollutants, or become an astronaut.

A uniform set of closing inventory prices for farm products can be used for several purposes. A net worth statement or balance sheet should be developed on or around January 1 to measure the financial progress of the farm from year to year. An up-to-date balance sheet is also requested by most lenders when a loan application is made. Inventory prices can be used to value the crops, livestock, and supplies that the farm has on hand at the time the statement is taken.

Summary of statewide evaluation in Iowa of alfalfa and corn yield response to applied sulfur fertilizers. On-farm, small-plot and field-length strip trial yield response data presented from 2005-2013.
K-12 schools often cite a lack of kitchen equipment and a shortage of skilled labor as barriers to the use of local foods in meals. A research project conducted in 2014–15 tested the benefits of a partnership between area school districts and the Northeast Iowa Food and Fitness Initiative’s (FFI) Iowa Food Hub — a non-profit food aggregator and distributor based in West Union, Iowa.
Summer pasture grazing will typically meet the energy and protein needs of cow-calf production with limited supplementation assuming there is an adequate supply of forage to satisfy the dry matter intake of cows.

The Iowa farmland rental market has undergone considerable change in the past few years. Following the 2013 Iowa land value peak, the declining commodity prices and farm income, changes in technology and changes in the demographics of farmland owners have created uncertainty with respect to the farmland rental market.

Although corn includes dent, flint, flour, and popcorn, sweet corn (Zea mays var. rugosa) is the first thing that comes to mind for many Americans. Sweet corn differs from field corn in that more sugar and less starch accumulates in the kernels. The five main types of sweet corn are standard sugary (su), sugary enhanced (se), shrunken-2 (sh2), synergistic (syn), and augmented supersweets (shA). These types vary in sugar content, texture, length of harvest period, storage life, and seed vigor/germination requirements.

One of the most important steps in soil testing is collecting the soil sample. The soil sample is the fi rst part of the soil testing process and the foundation for information derived from laboratory analyses, soil test interpretations, and recommendations. Also, soil sampling is the largest source of errors in the soil testing process.
Remember why you are taking soil samples -- to obtain information on which you can base recommendations and decisions concerning fertilizer, manure, and limestone use.
A comprehensive soil fertility and organic matter map for each fi eld is desirable as a basis on which to adjust fertilizer, manure, and limestone use. Over- or undertreatment may reduce profi ts. Best decisions can be made only if soil samples are representative of the areas sampled and accurately refl ect differences in the fi eld. You should remember that a very small amount of soil collected for samples will represent large fi eld areas. It is essential to select uniform sampling areas and to take a representative soil sample from each sample area.

What are terraces?
A terrace is an earthen embankment constructed across a field slope, typically following the contour, and can be designed to temporarily store runoff or convey runoff to waterways. Terraces break up the slope length of the field into multiple shorter slope sections, slowing the flow rate of runoff, reducing sheet and rill erosion and preventing the formation of ephemeral gullies. As terraces temporarily store and slowly infiltrate or discharge runoff, they conserve soil moisture, reduce streamflow by 5%, allow sediment to settle out, and reduce phosphorus loads by 77%. Terraces improve the ability to farm slopes and are designed based on equipment needs. Additionally, terrace vegetation can provide cover for wildlife. Terraces should be used in conjunction with other soil conservation practices on the landscape to prevent sedimentation.
