Application of organic amendments to restore soil health and productivity of a degraded soil.

Unagwu, Benedict Onyebuchi (2017-04)

Organic amendments (OAs) have the capacity to enhance physical, chemical, biological soil quality indicators (SQIs) and to improve soil productivity. This study investigated the effects of different OAs (Mushroom Compost, ...
Assessment of silt from sand and gravel processing as a suitable sub-soil material in land restoration: A glasshouse study

Mašková, Lucie; Simmons, Robert W.; De Baets, Sarah; Montero, Moran; Delmer, Aude; Sakrabani, Ruben (Elsevier, 2018-12-01)

Annually, sand and gravel processing generates approximately 20 million tonnes of non-commercial by-product as fine silt particles (<63 μm) which constitutes approximately 20% of quarry production in the UK. This study is ...
Best management practices to alleviate deep-seated compaction in asparagus (Asparagus officinalis) interrows (UK)

Mašková, Lucie; Simmons, Robert W.; Deeks, Lynda K.; De Baets, Sarah (Elsevier, 2021-07-03)

Field operations associated with UK asparagus production (re-ridging and intensive foot and vehicular trafficking of the wheelings) can result in severe deep-seated compaction in interrows, impacting on crop health and ...
Controlling soil erosion in a changing climate: evaluating suitable plant species in grassed waterway design.

Lees, Corina (2022-04)

Soil erosion is a global problem which needs mitigating due to the on-site and off- site impacts it causes. Soil erosion is set to become an even greater problem due to climate change. Climate change is likely to increase ...
Critical evaluation of compost erosion control blankets (CECBs) against conventional best management practices (BMPs) for the prevention and control of soil erosion, nutrient loss and storm water runoff from engineered slopes under simulated UK conditions

Mantovani, Dario (Cranfield University, 2010-03)

In recent decades increasing attention has been dedicated to issues of sustainable land management. Soil is essential for a number of functions and services which are central to the sustainability of agro-ecosystems and ...
A DNA-barcode biodiversity standard analysis method (DNA-BSAM) reveals a large variance in the effect of a range of biological, chemical and physical soil management interventions at different sites, but location is one of the most important aspects determining the nature of agricultural soil microbiology

Fernández-Huarte, Matías; Elphinstone, John G.; Adams, Ian P.; Vicente, Joana G.; Bhogal, Anne; Watson, Christine A.; Dussart, Francois; Stockdale, Elizabeth A.; Walshaw, John; McGreig, Sam; Simmons, Robert W.; Mašková, Lucie; Deeks, Lynda K.; Goddard, Matthew R. (Elsevier, 2023-07-06)

There are significant knowledge gaps in our understanding of how to sustainably manage agricultural soils to preserve soil biodiversity. Here we evaluate and quantify the effects of agricultural management and location on ...
Do cover crops give short term benefits for soil health?

Storr, Tom; Simmons, Robert W.; Hannam, Jacqueline A. (Association of Applied Biologists, 2018-12-31)

Cover crop use in the UK is increasing with establishment often before spring cereal crops. Therefore trials were implemented to assess two different cover crop mixtures for i) their ability to remediate soil compaction, ...
The effect of cover crops on soil quality indicators in a cereal and salad rotation.

Storr, Tom (2019-01)

Cover crop (CC)s influence soil function and thus affect crop yield and ecosystem services provided by soil. CCs are a relatively new soil management practice in U.K. agriculture, but are gaining in popularity amongst ...
Effects of cutting length and bud removal on root yield and starch content of cassava under rainfed conditions

Prasitsarn, Mapita; Polthanee, Anan; Trelo-ges, Vidhaya; Simmons, Robert W. (Cambridge University Press, 2017-03-27)

Bud removal of the cuttings at underground level has been claimed by cassava growers in Thailand as a method to increase cassava yield. This practise should be tested experimentally to explain the reason for yield increase. ...
Efficacy of mulch and tillage options to reduce runoff and soil loss from asparagus interrows

Niziolomski, Joanna C.; Simmons, Robert W.; Rickson, R. Jane; Hann, Mike J. (Elsevier, 2020-04-01)

In the UK, conventional asparagus cultivation practices on sloping land, erodible soils and increased frequency of extreme rainfall events combine to promote runoff generation and soil loss, particularly from interrows. ...
Efficacy of selected phosphorous sorbing materials (PSMs) to enhance the orthophosphate sorption capacity of filter socks

Cooke, A. L.; Simmons, Robert W.; Rickson, R. Jane; Sakrabani, Ruben (Wiley, 2020-11-18)

Agricultural phosphate (PO43‐) is a major cause of water quality compliance failures. Filter socks (FS) are a sediment‐control method proven to be effective at removing sediment and sediment bound‐P. Within the water and ...
Filter socks to mitigate sediment, sediment-bound phosphate and orthophosphate losses, from arable lands under extreme rainfall events.

Cooke, Alexandra (2018-02)

Agricultural diffuse pollution is a major environmental issue within the UK. Within England alone, sediment and phosphates in agricultural runoff account for 2967 rivers failing their Water Framework Directive (WFD) water ...
Impacts of long-term application of best management practices on yields and root carbohydrate content in asparagus (Asparagus officinalis) (UK)
