Weld Labs is a full service laboratory and we frequently test soil, manure, compost, and fertilizer. This integrated approach allows our customers to customize their soil amendment program according to compost/manure they have on site before extra fertilizer is purchased.

Our most popular packages are:

  1. The NPK Fertilizer package. At $54 this package includes Total Nitrogen by AOAC 970.02 as well as total phosphorus and potassium.
  2. The Basic Manure/Compost package. At $50 this package includes Total Kjeldahl Nitrogen, phosphorus, potassium, organic matter, moisture and solids content, and the C:N ratio.

Typical turnaround times for these packages are 4-5 business days.

There are many other analyses that can be added a la carte. For details or questions please see the services and pricing guide.
