Natural soils around Casper are generally of 3 basic types. 

1. Near the river sandy soils are often encountered. These sandy soils are usually well drained but low in fertility.

2. Most soils in Casper and the suburbs have a high clay content and drain rather poorly. They generally have moderate amounts of nitrogen and phosphorous and medium to high levels of potassium.

3. A small proportion of Casper area soils are poorly drained locations which have developed a whitish, salty surface. These last soils are unsuitable for normal plant growth and should be avoided for general gardens or to fill containers.

     The basic physical and, to a lesser extent, chemical properties of both clay and sandy soils can be modified to acceptable levels by blending with high quality decomposed organic matter (such as sphagnum peat moss, compost, forest waste products, clean aged manure and several other organic crop by-products. The first 4 mentioned are more likely to be found locally in acceptable forms at a reasonable price. But don't expect that all your problems are solved by knowing a few basic facts. I have spent over 50 years learning, teaching and doing original and practical research with soils and cannot truthfully say I know it all!​

    The best avenue of choosing the right soil and fertilizer regime is to consult with a lcoal commercial grower. 

     A professional soil test is one of the most valuable tools in assessing soil quality. There are numerous firms on the internet which can perform these tests - usually for less than $50.00, if you require only basic information and a short summation of recommendations. Natura Gardens uses these services on a regular basis and we annually require one for every company which supplies us with soil.  Wyoming residents are sometimes able to have soil analyzed by the University Extension Service for free or only a token fee. Call the Natrona County Agricultural Resource and Learning Center if this is something you wish to do- (307) 235-9400 or go to their website- http://www.natrona.net/19/Extension-Services-4-H
