Nutrients

Nitrogen 3% is the mineral element used in the greatest quantity by turf. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. The addition of Nitrogen fertilizer can encourage ideal conditions for a dense attractive lawn.

Phosphorus 18% The proper level of phosphorus in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus fertilizer effects on turf are usually more subtle and, while not as readily visible, are still very important.

Potassium 18% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium fertilizer plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. Potassium can enhance the plant’s endurance to stress if a deficiency is present.

Info 

For best results, water the lawn for 20 minutes within 24 hours of application. Water is essential for maintaining your lawn, and your lawn should receive 1-2 inches of water per week. Fertilizer will not treat a lawn that is suffering from disease, pests, weed infestations, or drought, and these conditions should be treated separately.

Not recommended to apply this product during drought, or drought-like conditions.

Great sound deadening material with easy installation.
Size: 36 sqft, Size: 36 sqft
This sound-deadening mat was easy to install on the roof of my Toyota FJ Cruiser. It significantly stiffened the roof and dramatically reduced the wind noise inside the vehicle caused by my roof rack and lights. I can actually carry on a conversation again without shouting while driving on the freeway. The 36-square-foot package was enough for my application, with about three sheets left over. The tiles adhered well to the metal without any special surface preparation. I only wish I had done this sooner.

Gama Sonic Solar Lights: Built to Last and Guaranteed
Number of Items: 2
These lights are nice and bright and stay on all night. I have other Gama Sonic solar lights also. One of them, which I didn't buy from Amazon, had a problem so I contacted Gama Sonic directly because they have a 2-year warranty. They responded immediately and I got it fixed and now I'm happy with it. I will keep buying their solar lights because they make good quality solar lights and have a 2-year warranty.

Very strong construction--no plastic
Number of Items: 2
Expensive, but appears to be very well made. The lights are made of aluminum, so the support is sturdier than the usual plastic. The poles are in two parts, so you have a choice of heights the light is above the surface. Battery replacements are expensive, but you should get two years or more from a battery. You have a choice of a quite bright white light or a less bright yellow light.
