Have questions? We have answers. Check out a list of our most frequently asked questions below—if you don't find the answers you need, contact us to learn more.

Should I use alternative sources of fertilizer (ie: chicken litter)?

We feel there is tremendous value in using other fertilizer options, especially different manure sources. We can evaluate your needs and help determine if litter or other manure could be a good fit for your operation.

Do you sell any products?

No, G&K does not offer any retail products in conjunction with our consulting services. We feel that the option to stay neutral and not tied to any particular product helps us to remain unbiased and provide a third-party perspective that our clients value and trust.

Should I plant cover crops?

Cover crops are a great approach to solving some conservation challenges and provide soil health benefits that are difficult to replicate with other practices. However, cover crops aren’t necessarily a good fit for every operation. The decision whether or not to employ cover crops on your farm needs to be a comprehensive decision that evaluates many facets of your operation. We have encouraged some growers to consider using cover crops while others we have expressed concern that it may not be the best fit for them. We can help you to make those types of decisions.

What are ideal nutrient levels for my field?

There isn’t a perfect set of values that can be blanketly prescribed to all different fields. We take many factors into consideration when determining what would be the right nutrient strategy for each field. We will work with each grower to optimize a nutrient plan that best suits their operation.

Why should I use zone management rather than grid sampling to examine soil fertility?

The practice of zone management helps to ensure that areas within the field of the same soil type or yield environment are sampled together and treated accordingly. Grid sampling does not account for the variability found within many fields of varying elevation and soil structure. Zone management allows us to accurately prescribe fertility management decisions with the confidence of knowing that all of the areas within the management zone will behave similarly and those areas outside that zone may need something different. Field performance doesn’t occur in perfect squares. Being representative is what matters and zones do that best.
