Summary
Abstract: Two major properties which determine weed seed germination are soil temperature
and moisture content. Incident radiation is the primary variable controlling
energy input to the soil system and thereby influences both moisture and

proper instrumentation to measure solar radiation directly. To overcome this
shortcoming, an ... View entire text
