The all natural organic way to improve native soils is to start with Black Kow composted cow manure. The "Mature Manure" Black Kow has 10X more nutrients than typical garden soil and 4 to 6X more cow manure than other brands. Black Kow cow manure holds water and nutrients in the soil around the roots. The roots can use the water and nutrients when needed instead of letting the nutrients leach through the soil. Black Kow cow manure helps break up those soils so that water and nutrients are available to the plant when needed. Black Kow cow manure contains millions of beneficial bacteria. These bacteria convert nitrogen and other nutrients into an easily available form for the plant. It is organic and contains nutrients that are released slowly without burning tender roots. These nutrients and moisture are held in the soil around roots until the plant needs them.
